How to stop screen swap while using zoom

[fhiring]

I wanna stop my kids to use other applications, while using zoom. especially they watch YouTube shorts and in background zoom audio stay active thus I can't figureout if they are in class room or watching something else.

Please provide a solution to restrict them not to away from class room during their session.

Sorry... Zoom is "just an app" and doesn't control the host computer.  if the host computer (Windows, Mac, Linux) allows app switching, there's nothing Zoom can do about it.
