Good Morning! You may be able to do this using The Tween Machine by doing a scale and position tween on each door, they would have to be on their own layers to do this but then could be merged down together again :)
Also you may need to scale down (start with the doors closed and then scale them down to look open) this way the tool has more pixels to work with.
It's a bit hard to describe in text actually 😆 and I'm not sure if it would look excatly how this looks but it would give you a basic animation to start refining! 😀
