Why Share Screen in my plugNmeet classes not working?

[chrokemali]

I am using Ubuntu 24.04 to host PlugNmeet and PHP SDK to join the moderator and participants in the conference. Although I have enabled "Screen Sharing" in both the "room settings" and the moderator and participant join file settings, the "Screen Sharing" button never works.
A part of join file:

...
$roomMetadata = array(
        "room_features" => array(
                "allow_webcams" => true,
                "mute_on_start" => true,
                "allow_screen_share" => true,
...

And in other part:

...
        "default_lock_settings" => array(
                "lock_microphone" => true,
                "lock_webcam" => true,
                "lock_screen_sharing" => false,
...

Any help would be appreciated.

I think you maybe using iframe to embed the meeting in your website or app, if that's the case, you must add capture screen in allow attributes of the iframe.
