I have no idea if this one day will contribute to virtual zoom chat. If you are wondering how this works well its pretty simple this uses one of scratches extensions called video sensing. This has a timer for 5 seconds if it does not detect any motion or mouse down or any key pressed it will say your AFK. Also, if you press any key or even touch anything it will say your not afk. And with all that covered have fun with this AFK detector. (:
