Order it and install it.
The panel can only be removed when the door is opened but you can pry it back enough to get some working room with the door closed if it is stuck shut.
They will show you drawings you point to the part.
First you will need to pry back the door panel so you can access the inside of the door.
Start by removing the two screws that secure the panel to the door.
Door interior parts can be a fiddly job that scratches up your hands like you had a cat fight.
Just take your time.
