Multiple Windows are shared and the previous window is overwritten by the latest window

[trookie2000]

In my program, each process is shared individually via getDisplayMedia() and controlled remotely by emulation of keyboard and mouse events.

But there is a problem, when I control window 1 remotely, if window 1 is overwritten by window 2, then actions (like mouse clicks) in window 1 will completely fail

Is there a way to place the shared video window at the top of my desktop when I click the full screen of a video, similar to z-index

The red rectangular box is the part of window 2 covering window 1, in which case the operation of remote control window 1 being covered will fail
