Some total c**t has opened their door on my rear panel

all be it very slightly so I need a trip to dent devils to remove.. fingers crossed ! But how do you remove the rear carbon trim panel ? Does anyone know if the carbon bit comes off on its own and then the surrounding panel any help would be much appriciated
Is the metal behind quite accessible no sound deadening etc ?
The pic below shows the very slight crease picked out by the window frame reflection
