So I am a newbie at Meteor, and in Bigbluebutton 2.4, I have to make a simple message that goes to all the users in a meeting. even without the meeting criteria I still cant get them on my frontend In the code, I can subscribe to the ptzmessage and I see it in `Meteor.connection._subscriptions list on the browser

componentDidMount() {
    const { onVideoItemMount, cameraId } = this.props;

    console.log("subscribing")
    Meteor.subscribe('ptzmessage').ready()

    this.subscription = Meteor.subscribe('ptzmessage');
    // Retry after 5 seconds if not ready
    this.retryTimeout = setTimeout(() => {
        if (!this.subscription.ready()) {
            console.log("Retrying subscription...");
            this.subscription = Meteor.subscribe('ptzmessage');
        }
        console.log(" subscription completed...");
    }, 5000);

    this.tracker = Tracker.autorun(() => {
      console.log("Fetching messages...");
      const messages = PtzMessages.find({}).fetch();
      this.setState({ messages });
      console.log('Received Messages:', messages);
    });

this is the Api file in import/api/ptzmessage and imported in the frontend and the backend

import { Mongo } from 'meteor/mongo';

// Define PtzMessages collection
export const PtzMessages = new Mongo.Collection('ptzmessages');
if (Meteor.isServer) {
  PtzMessages._ensureIndex({ meetingId: 1 });
}

this is the server code when I press button send message it adds it in the collection

import { Meteor } from 'meteor/meteor';
import { PtzMessages } from '../index.js';

Meteor.publish('ptzmessage', function () {
  console.log(`Client ${this.connection.id} subscribed to ptzmessage`);

  return PtzMessages.find();
});

Meteor.methods({
  sendPtzMessage(message) {
    console.log("#####################################################################################api hit")
    PtzMessages.insert({ text: message, createdAt: new Date() }, (err, res) => {
      if (err) {
        console.error("Insert Error:", err);
      } else {
        console.log("Message inserted successfully:", res);
      }
    });
  }
});

infact in the frontend Meteor.connection._mongo_livedata_collections.ptzmessages.find().fetch(); get me the latest messages, but I don't get them in real-time on the Tracker. Stuff like this is done in other code that works what am I doing wrong?
