How to use the @vue/devtools.connect function in @vue/devtools

import devtools from '@vue/devtools';
import MeetingSchedulerView from 'view/MeetingSchedulerView';
import { INTERNAL_EVENTS } from 'constants';

/**
 * @vue/devtools will be replace with an empty module by webpack null-loader for
 * production build.
 */
if (devtools && devtools.connect) {
  devtools.connect('localhost', 8098);
}

if (window.parent !== window) {
  // only execute this script when launched inside iframe
  const id = window.location.hash.substr(1);
  setTimeout(() => {
    const scheduler = new MeetingSchedulerView({
      id,
    });

    scheduler.messenger.connect(window.parent);
    scheduler.messenger.send({
      event: INTERNAL_EVENTS.VIEW_LOAD,
    }, '*');
  }, 0);
}

const setupDevtools = () => {
      devtools.connect('ws://localhost', port, {
        app: this,
        showToast,
        io() {
          try {
            const SocketIO = require('nativescript-socketio').SocketIO
            const address = `http://${getServerIpAddress(host, port)}`
            let socketIO = new SocketIO(address, {debug: debug})
            socketIO.connect()

            return socketIO
          } catch (error) {
            console.log(error)
          }
        }
      })
