Directly letting users join meeting via browser without further interaction.

functions.php

<?php
/**
 * Paste below code to your functions.php file in your theme.
 *
 * NOTE: If user is not logged in this code will not work because when joining a meeting from browser - User name is a required field and since
 * this below code directly triggers the join button on load. Users will not be able to join the meeting without a name.
 *
 * The reason this would work with logged in users is because username is already selected in the join via browser page if a user is logged in.
