How do I get the rear door skin off? on 2008 Buick LaCrosse

My rear door will not open. How do I get the door skin off when the door is in the closed position? I have the back seat out, but where are the screws holding the door and are the clips the type you can just pull outward?

door panels are not designed to be removed with the door
closed. most of the time this happens, the door panel will be destroyed when removed.
