Swift Escape roof light blind surround

[Moss]

Anyone know how you remove the over cab sky light furniture surround. Mine has fallen on one side. It has pulled the bottom left corner screw out and I can’t work out how to get to the others to remove it from the roof to repair. If I leave it it’s putting strain on the other screws. I’ve tried attaching it with heavy Velcro but just pulls away after a few minutes. I’m now resorting to holding it up with a torch. I’ve attached pictures
