Glass door does not close properly - How to adjust?

Hello everyone, we have the problem that our glass door does not close properly or only closes with difficulty. Waiting for the person who installed it makes no sense, so I would like to try to adjust something on the door myself. Unfortunately, I have not found any proper information on how to fix my problem. As mentioned, the door only closes with great difficulty and you have to pull it shut firmly every time for the latch to engage. What can be done? Which screw do I have to turn or what can I do? I have attached photos of the hinges, can I adjust something there?!? Thanks

Hello! Diagnosis from a distance is quite difficult! If the door can only be closed by pulling it, it must be further out on the side of the hinges. This is probably adjusted by the Allen screw (visible in the photo). When in doubt, have the courage to try!!!

Tried it today but gave up in frustration. Thought one could say concretely what needs to be done here. But I guess I’ll have to take another look at it calmly sometime.
