joining meeting zoom meeting on laptop monitor and my camera picture is on the 2nd monitor

I am using a Linux operating system. If I join someone's meeting 2 on a call.  When I join the right screen is the same and the left will have the host on half of panel screen and a blank black screen on the other side and my name Garry in blank. I want to delete the zoom app and reinstall. I do not know how to delete the zoom app then try to load the app again
