Didn't want to clutter another thread which mentioned people in zoom calls having a background picture of bookcases.
If you can get the green screen background thing to work well you don't have to use your own library or even picture of it as a background.
On a recent family call my nephew apperaed to have rearranged his livingroom. However it was a background picture of someone else's. During a work call someone had logged in then gone away leaving the camera showing her livingroom. So all her work colleagues screen grabbed it and used it as their background. Try it on your boss?
