When hosting a Webinar attendees can use the 'Join stage' feature to speak and ask questions at your event.

Can I disable Join Stage?

Yes. By default Join Stage is switched on for attendees, however if you want to disable this feature go to Webinar > Settings > Permissions > Access > Media.

If you switch audio, video and screenshare to 'not allowed' then 'Join stage' button won't appear as an option during your webinar to attendees.
