Zoom apps with bombers

One of the things that has been great about Zoom is the security settings in which to make sure you don't have a Zoom bomber.  For instance you could make sure that a participant cannot share a screen or whiteboard, etc.

It recently came to my attention that any participant can begin to share an app during a meeting.

I have done a lot of searching and cannot find a way to turn that off. 

Can you please provide assistance?
