I've been playing around with OBS and Zoom lately as well. Prior to a meeting, I pre-recorded a couple of minutes of me watching the screen. I used OBS to switch to this looped pre-recording whenever I wanted to eat/drink or get out of my chair to stretch etc during the meeting.
It was mostly just to satisfy my curiousity on how difficult it is to do (it's easy) and whether anyone noticed the looping (no one did). But what I did find interesting was that I found it immensely 'freeing' to be able to participate in the meeting without being observed - there is something about knowing I'm on camera that I find taxing that I don't get in a face to face meeting.
