Can not Join Conference

I'm trying to join a conference using following block, but it didn't worked.

Js file

/* global $, JitsiMeetJS */

let connection;

const options = {
    hosts: {
        domain: 'meet.jit.si',
    },
};
const confOptions = {
    openBridgeChannel: true
};

JitsiMeetJS.init();
connection = new JitsiMeetJS.JitsiConnection(null, null, options);

function onConnectionSuccess() {
    console.log("onConnectionSuccess")
    const room = connection.initJitsiConference("TestDemo1234567890", confOptions);
    room.on(JitsiMeetJS.events.conference.TRACK_ADDED, onRemoteTrack);
    room.on(JitsiMeetJS.events.conference.CONFERENCE_JOINED, onConferenceJoined);
    room.join();
}

function onConnectionFailed() {
    console.log("onConnectionFailed")
}

function disconnect() {
    console.log("disconnect")
}

function onRemoteTrack() {
    console.log("onRemoteTrack")
}

function onConferenceJoined() {
    console.log("onConferenceJoined")
}

connection.addEventListener(
    JitsiMeetJS.events.connection.CONNECTION_ESTABLISHED,
    onConnectionSuccess);
connection.addEventListener(
    JitsiMeetJS.events.connection.CONNECTION_FAILED,
    onConnectionFailed);
connection.addEventListener(
    JitsiMeetJS.events.connection.CONNECTION_DISCONNECTED,
    disconnect);
connection.connect();

JitsiMeetJS.createLocalTracks().then(onLocalTracks);
