Unfortunately, you do have to remove the door panel however, these are not too bad.
Here is a guide that shows how to do this in general:

I also attached the document from the manual but unfortunately this is not terribly detailed but it shows the location of all the clips.
If you don't feel comfortable doing it, it is probably best to have someone else do it because they can break and they are not cheap.
Let me know if you have questions. Thanks
