GLS rear grab handle with light
 

I am a bit (quite a lot) disappointed by MB. We were travelling from holidays and after 6 hours sitting behind the driver I just wanted to move a bit my bottom so I wanted to help myself just grabbing the handle over the door.
Something cracked and I fortunately released it before breaking both sides and tearing out all the wires.

**** there is nowhere warning not to touch or even to use this handle! **** (it is just probably demo...)

I attach two photos. One is with woman's painted nails and the second is camera watching inside the space between the grab handle and the roof.

What might have been cracked? How to remove it safely on the right side? Is it possible to glues some pieces together with glue for plastics so it can continue to work as a nice demo inside the car?

thank you for the help!
