How to detect if user is screen sharing in a Chrome Extension?

I would like my chrome extension to do something unless a user is screen-sharing his/her screen or window via getDisplayMedia. Is it possible to query specific tabs or something to detect any kind of screen sharing performed via web-based applications like Team viewer, Zoom, Google Meet, Facebook Messenger, Viber, etc. in a chrome extension?

Netflix already does this without using any sort of chrome extension (albe开发者_运维问答it only when sharing entire screen, not a window or tab). The Netflix video goes black. So there must be some way with privileged access through a chrome extension?
