Once that piece is out, it exposes a small screw. I am pointing at it. If you want to remove the plastic outer trim, you’ll have to remove this screw. In order to remove this screw, you’ll have to detach the air bag from the seat frame since it is obscured by the seat back. It’s possible to remove it with an angled t25 tool, but I don’t have that. Removing the air bag is easy at this stage.
