How do you remove the door handle and trim on the right rear van doors?

[captaincaveman]

I am looking to install an aftermarket keyless entry system on my NV2500.

 

In so doing, I'm trying to remove the door panel on the right rear van door, specifically, removing the door handle and  trim.  I don't see anything holding it in, and suspect it just clips in.  But I don't want to break it so I thought I would check if there was a trick to getting the door trim off.
