Zoom does as well. It kinda works, but it's not perfect at detecting you vs. stuff behind you. I have a high-backed chair and it thinks the chair is part of my head sometimes. Zoom also has a setting that allows you to tell it if you have an actual green screen behind you.

One thing I hate about Zoom is that it allows meeting organizers to default webcams to on... which can be a surprise to those who aren't expecting it.
