One of the paint corrections that will be done on my car this summer by the paint shop is the rear hatch near the lock.

I would like to ask you for advice on how to get to the hatch lock, i.e. I mean some instructional video or a few photos showing how to dismantle it.
This lock opens in my car correctly, but the lock tongue does not deflect, every time after opening the hatch I have to deflect it with my finger.
I think that if it could be dismantled, then maybe it could be repaired/lubricated.
Because it's rather impossible to buy a new tailgate lock like that...





Since the license plate light lenses are broken, I found a set of two new ones in this store, which I will buy:

Here is a video showing how they are installed:
