Thanks @hermesf. I changed the page attributes and it looks better now. Please look at the below use case:
> 100 attendees on the call
> Host is presenting and attendees are not allowed to speak, but their camera is visible
> Host selects one of the attendees to speak to, so the attendee is presented alongside the host on the main screen.
> Attendees can text chat, similar to youtube live chat.
Please let me know how to go about this. Thanks.
