here in odoo 13 I create a website template. inside this template i added a button. now I want to show a message after clicking this button through js. but in my code its not working please help me regarding this issue. 

js code:

odoo.define('spiralworld_agm_webinar.zoom_button', function (require) {
    "use strict";

    // Wait for the document to be fully loaded
    $(document).ready(function () {
        // Find the "Join Meeting" button by its ID
        var joinMeetingButton = document.getElementById('joinMeetingButton');

        if (joinMeetingButton) {
            // Add a click event handler to the button
            joinMeetingButton.addEventListener('click', function () {
                // Display a message in the console
                console.log("Button clicked - Join Meeting event handled.");
                // You can add more code here to perform additional actions
            });
        }
