                    $f3->push('init.js', 'Meetings');
                    $f3->set('name', $name);
                    
                    $f3->set('joinUrl', 'meeting/' . $meetingId);

 let joinMeeting = function () {
    $(document).on('click', '.join-meeting', function (e) {
        e.preventDefault();

        let meetingId = data.meeting_id;

        $.ajax({
            type: 'GET',
            url: '/meeting/' + meetingId,
            contentType: 'application/json',
            success: function (result) {
                if (result.joinUrl === 'none') {
                    noty({text: 'Could not join the requested meeting.', type: 'error'});
                } else {
                    setInterval(window.open(result.joinUrl, '_blank'), 5000);
                }
            },
            error: function (jqXHR) {
                noty({text: 'Application error', type: 'error'});
            }
        });
    });
};


return {
    //main function to initiate the module
    init: function () {
        joinMeeting();

    }
}
}();

If you render a page, the page is loaded and the script is reloaded again and set interval is never ejecuted.
