California Ocean T6 (2018) rear hinged cupboard door

[mikeb4472]

Hi - juts inside the tail door is the cupboard with shelves and which houses the gas bottle. The hinged door has lugs top and bottom which hook it closed. I've managed to snap those off. I now have a VW repair kit for the door but I can't work out how to take the old mechanism apart or put the new one on!! Photos show the door, the problem and the replacement kit..... Anyone have any instructions? I am guessing I may have to prise/click the open/close handle off but don't want to risk that without knowing what I am doing!!
