yes...add to the desktop, like zoom as well, with the space bar.
Yes, this feature is much required for the mobile/tablet App. Something like a floating unmute button, that does not vanish but always remains on screen, would be of great help.

spacebar temp unmute is the way to go here
Add the space bar unmute like zoom - unmute yourself while holding space bar, but automatically mute again when released. It prevents people from forgetting they are muted/unmuted.
Zoom allows you just to press spacebar to unmute - this is much easier and quicker and gives a better flow to lessons and conversations
Or a mute/unmute button always present (not on a toolbar that hides when there is no action on the screen)
