As you want to remove the whole <p> element from the textHtml string. You can easily achieve it by using RegEx with the help of String.replace() method.

Live Demo :

const textHtml = "<h1>What events are you looking for today?</h1> <p>Find more events you want!</p>"

const res = textHtml.replace(/<p>*.*<\/p>/, '');

console.log(res);

<h1>What events are you looking for today?</h1>

You're storing multiple HTML elements in a string, but you'll likely want to wrap multiple elements in a <Fragment>, i.e.:

import { Fragment } from 'react'

const titleAndP = (
   <Fragment>
      <h1>What events are you looking for today?</h1>
      <p>Find more events you want!</p>
    </Fragment>
 )

You need to wrap the code. You can do it with empty tags (typical in ReactJS)

const html = (
    <>
        <h1>title</h1>
        <p>paragraph</p>
    </>
)

Try adding this under your code

<Markup content={textHtml} />
