Can't extend my custom gutenberg block

I have been trying to extend some custom blocks I coded along with core blocks to support custom CSS.

This is how tried to extend the block attributes

const {assign} = lodash;

const {__} = wp.i18n;

const {hasBlockSupport} = wp.blocks;

const {PanelBody} = wpponents;

const {createHigherOrderComponent} = wppose;

const {InspectorControls} = wp.blockEditor || wp.editor;

const {Fragment} = wp.element;

const {addFilter} = wp.hooks;

/**
 * Internal dependencies.
 */
import './style.scss';

import CSSEditor from './editor.js';

import './inject-css.js';

const addAttribute = (settings) => {
    console.log(settings);
    if (hasBlockSupport(settings, 'customClassName', true)) {
        settings.attributes = assign(settings.attributes, {
            hasCustomCSS: {
                type: 'boolean',
                default: false
            },
            customCSS: {
                type: 'string',
                default: null
            }
        });
    }

    return settings;
};

const withInspectorControls = createHigherOrderComponent((BlockEdit) => {
    return (props) => {
        const hasCustomClassName = hasBlockSupport(props.name, 'customClassName', true);
        if (hasCustomClassName && props.isSelected) {
            return (
                <Fragment>
                    <BlockEdit {...props} />
                    <InspectorControls>
                        <PanelBody
                            title={__('Additional CSS')}
                            initialOpen={false}>
                            <CSSEditor
                                clientId={props.clientId}
                                setAttributes={props.setAttributes}
                                attributes={props.attributes}
                            />
                        </PanelBody>
                    </InspectorControls>
                </Fragment>
            );
        }

        return <BlockEdit {...props} />;
    };
}, 'withInspectorControl');

addFilter('blocks.registerBlockType', 'attire-blocks/custom-css', addAttribute);
addFilter('editor.BlockEdit', 'attire-blocks/with-inspector-controls', withInspectorControls);

The thing is, custom attributes I introduced (hasCustomCSS and customCSS) are applied to core blocks are not applied to blocks I made! Also, see the console.log(settings);. This only prints core blocks, mine are not shown.

EDIT: This is how I am applying the attributes:

add_action('wp_head', array($this, 'apply_custom_css'));



  public function apply_custom_css()
    {
        if (function_exists('has_blocks') && has_blocks(get_the_ID())) {
            global $post;

            if (!is_object($post)) {
                return;
            }

            $blocks = $this->parse_blocks($post->post_content);

            if (!is_array($blocks) || empty($blocks)) {
                return;
            }

            $style = "\n" . '<style type="text/css" media="all" id="atbs-ccss">' . "\n";
            $style .= $this->get_block_custom_css($blocks);
            $style .= "\n" . '</style>' . "\n";

            echo $style;
        }
    }





  public function get_block_custom_css($inner_blocks)
    {
        $style = '';
        foreach ($inner_blocks as $block) {
            if (isset($block['attrs'])) {
                if (isset($block['attrs']['hasCustomCSS']) && isset($block['attrs']['customCSS'])) {
                    $style .= $block['attrs']['customCSS'];
                }
            }

            if ('core/block' === $block['blockName'] && !empty($block['attrs']['ref'])) {
                $reusable_block = get_post($block['attrs']['ref']);

                if (!$reusable_block || 'wp_block' !== $reusable_block->post_type) {
                    return;
                }

                if ('publish' !== $reusable_block->post_status || !empty($reusable_block->post_password)) {
                    return;
                }

                $blocks = $this->parse_blocks($reusable_block->post_content);

                $style .= $this->get_block_custom_css($blocks);
            }

            if (isset($block['innerBlocks']) && !empty($block['innerBlocks']) && is_array($block['innerBlocks'])) {
                $style .= $this->get_block_custom_css($block['innerBlocks']);
            }
        }
        return $style;
    }

Edit 2 : the CSSEditor component

const CSSEditor = ({attributes, setAttributes, clientId}) => {
useEffect(() => {
    if (attributes.customCSS) {
        customCSSRef.current = (attributes.customCSS).replace(/.atbs-ccss-[a-zA-Z0-9_-]*/g, 'wrapper');
    } else {
        customCSSRef.current = 'wrapper {\n}\n';
    }

    editorRef.current = wp.CodeMirror(document.getElementById('atbs-css-editor'), {
        value: customCSSRef.current,
        autoCloseBrackets: true,
        continueComments: true,
        lineNumbers: true,
        lineWrapping: true,
        matchBrackets: true,
        lint: true,
        gutters: ['CodeMirror-lint-markers'],
        styleActiveLine: true,
        styleActiveSelected: true,
        extraKeys: {
            'Ctrl-Space': 'autocomplete',
            'Alt-F': 'findPersistent',
            'Cmd-F': 'findPersistent'
        }
    });

    editorRef.current.on('change', () => {
        const regex = new RegExp('wrapper', 'g');
        customCSSRef.current = editorRef.current.getValue().replace(regex, `.${classArRef.current}`);

        if (('wrapper {\n}\n').replace(/\s+/g, '') === customCSSRef.current.replace(/\s+/g, '')) {
            return setAttributes({customCSS: null});
        }
        setAttributes({customCSS: customCSSRef.current});
    });
}, []);

useEffect(() => {
    let classes = getClassName();

    setAttributes({
        hasCustomCSS: true,
        className: classes
    });
}, [attributes]);

const getClassName = () => {
    let classes;

    const uniqueId = clientId.substr(0, 8);

    if (null !== customCSSRef.current && ('wrapper {\n}\n').replace(/\s+/g, '') === customCSSRef.current.replace(/\s+/g, '')) {
        return attributes.className;
    }

    if (attributes.className) {
        classes = attributes.className;

        if (!classes.includes('atbs-ccss-')) {
            classes = classes.split(' ');
            classes.push(`atbs-ccss-${uniqueId}`);
            classes = classes.join(' ');
        }

        classArRef.current = classes.split(' ');
        classArRef.current = classArRef.current.find(i => i.includes('atbs-ccss'));
    } else {
        classes = `atbs-ccss-${uniqueId}`;
        classArRef.current = classes;
    }

    return classes;
};

const editorRef = useRef(null);
const customCSSRef = useRef(null);
const classArRef = useRef(null);

return (
    <Fragment>
        <p>{__('Add your custom CSS.')}</p>

        <div id="atbs-css-editor" className="atbs-css-editor"/>

        <p>{__('Use')} <code>wrapper</code> {__('to target block wrapper.')}</p>
        <p>{__('')}</p>
        <p>{__('Example:')}</p>

        <pre className="atbs-css-editor-help">
            {'wrapper {\n    background: #000;\n}\n\nwrapper img {\n    border-radius: 100%;\n}'}
        </pre>

        <p>{__('You can also use other CSS syntax here, such as media queries.')}</p>
    </Fragment>
);

};
