如何让用户等待加入，直到会议组织者首先加入

我正在实现一个视频会议室，用户可以在其中创建视频会议并邀请其他用户。

现在我想确保用户不能加入会议，直到会议组织者打开房间。

我有以下代码，但它不工作。会议组织者可以打开会议室，但当用户点击"加入会议"时，它不会加入。

// https://github.com/muaz-khan/RTCMultiConnection
var rmc = new RTCMultiConnection();
rmc.userid = "<?php echo $user->fname . ' ' . $user->lname . ' (' . $user->username . ')' ; ?>";
rmc.session = {
    video: true,
    audio: true,
    data: true
};
var room_status = 0; //room closed
$('#open-room').click(function () {
    // http://www.rtcmulticonnection.org/docs/open/
    room_status = 1; //room opened
    rmc.open();
    rmc.streams.mute({video : true});
    document.getElementById("on-off-video").style.color= 'red';
});
$('#join-room').click(function () {
    if(room_status == 1) {
        // http://www.rtcmulticonnection.org/docs/connect/
        rmc.connect();
        rmc.streams.mute({video: true});
        document.getElementById("on-off-video").style.color= 'red';
    }
    console.log("Waiting for meeting organizer");
});
// display a notification box
window.addEventListener('beforeunload', function () {
    return 'Do you want to leave?';
}, false);
// leave here
window.addEventListener('unload', function () {
    rmc.leave();
}, false);
rmc.onMediaCaptured = function () {
    $('#share-screen').removeAttr('disabled');
    $('#open-room').attr('disabled', 'disabled');
    $('#join-room').attr('disabled', 'disabled');
};
//chat
rmc.onopen = function (event) {
    //alert('Text chat has been opened between you and ' + event.userid);
    document.getElementById('input-text-chat').disabled = false;
    room_status = 1;
};
//end of chat
$('#disconnect').click(function () {
    room_status = 0; //room closed
    rmc.leave();
    setTimeout("location.href = '../';",2000);
});
//to know the stream type
rmc.onstream = function (e) {
    if (e.type == 'local') {
        // alert("the stream is local");
    }
    if (e.type == 'remote') {
        // alert("the stream is remote");
    }
    if (e.isVideo) {
        var uibox = document.createElement("div");
        uibox.appendChild(document.createTextNode(e.userid));
        uibox.className = "userid";
        uibox.id = "uibox-" + e.userid.replace(/ |'(|')/g, '');
        document.getElementById('video-container').appendChild(e.mediaElement);
        document.getElementById('video-container').appendChild(uibox);
    }
    else if (e.isAudio) {
        document.getElementById('video-container').appendChild(e.mediaElement);
    }
    else if (e.isScreen) {
        $('#cotools-panel iframe').hide();
        $('#cotools-panel video').remove();
        document.getElementById('cotools-panel').appendChild(e.mediaElement);
    }
};
//removes the div containing the userid of the user who is leaving
rmc.onleave = function (e) {
    $('#' + "uibox-" + e.userid.replace(/ |'(|')/g, '')).remove();
};
