2008 CR-V Body Panel Dislodged

The triangular and curved body panel below the right-rear tail-light
cluster has been disloged in a minor colision. It appears to attach
through a multitude of male tabs that insert into receivers on the
adjacent body parts.

What is my best course of action: (1)Honda dealer (who says they do
not do body work) but might be able to "worry" it back together, (2)
body shop, or (3) get my sore and stiff body on the ground and try
worry the piece back into place myself?

Any advice on how to go about the last option would be appreciated.
