1994 Toyota Camry tailights

I need to replace a brake light, in my other cars it was as simple as accessing the back of the assembly, turn the bulb holder to release, replace the bulb and put it back together. Done

When I pilled back the trunk liner on my Camry I see that on this model that's not going to be the case. I don't want to break anything so can you guide me from here.

Thanks Guys.
