ᐅ Glass door does not close properly – how to adjust it?

Hello everyone, we have the issue that our glass door does not close properly or only closes with difficulty.
Waiting for the person who installed it doesn’t make much sense, so I would like to try to adjust the door myself.
Unfortunately, I couldn’t find clear information on how to fix this problem.
As mentioned, the door closes very stiffly, and you have to pull it hard every time to make the latch engage. What can be done? Which screw should I turn, or what else can I do? I have attached photos of the hinges. Is it possible to make adjustments there? Thanks.

Hello! Diagnosing the issue remotely is quite difficult! If the door can only be closed by pulling it in, it needs to be adjusted outward on the hinge side. This is usually controlled by the Allen screw (visible in the photo). When in doubt, don’t hesitate to try it out!

I tried it today but gave up in frustration.
I thought it would be possible to clearly explain what needs to be done here. But I guess I will have to take another closer look at it sometime later.
