Fuel flap release - Laguna Mk2

Evening folks,



A while back my fuel flap release packed in and I had a read on here that you can pull the little black ringpull through the boot and it'll open.



However it would appear the previous owner already had this issue and had broken the rullpull.



I have the new part but as stupid as this sounds, I cant see how the thing is mounted lol I cant see any screws or clips holding it in place.



Any ideas people?



Thanks in advance



Kenny
