Ceiling Lamp with 2-switch Control: 4-point, Brown & Blue Wires, 4 Ceiling Cables - DIY Guide

Good evening everyone
Gentlemen - a woman asks for help, so like a cow in a ditch.
The problem is this: I bought a lamp that supposedly can be divided into 2 switches. The lamp is 4-point and upon arrival home zonk ... The cables from the lamp look like this:
brown are 4, blue are also 4. Brown to one cube, blue to the other.


On the other hand, there are 4 cables sticking out of the ceiling: gray, black, brown and yellow. As far as I know, according to the markings, they are led out.
The concept is that when one key is turned on, 2 light bulbs light up, when the other one, 2 more. Is it possible with this lamp at all, or have I been fooled?

If so, I will be very grateful for your help.
Unfortunately, the lack of a reasonable guy at hand forces me to be independent

From the description, I conclude that it is a 5-minute job with a cup of tea
The lamp has four luminaires with bulbs, two blue and brown wires come out of each luminaire, so I more or less drew it for you. Now you need to disconnect the cube with the brown wires. If you want two luminaires + two to turn on, you need to divide the brown wires. You need two cubes, one gives you two brown wires and the other two. You don't touch the blue ones.
Now let's deal with the wires from the ceiling. I suspect that black is phase and brown and gray is N and yellow is earthing, i.e. PE. You must have t. neon.
If my suspicions are correct, now we need to start connecting the lamp to the wires from the ceiling.
How did you divide these four brown wires into two cubes of two wires, now: We connect the blue wires to the gray one from the ceiling with a cube, and the brown wires, i.e. our two cubes, to: one to black and the other to brown.
Yellow will certainly be PE, i.e. this grounding should be connected to the housing if there is a terminal for connecting the protective conductor, i.e. this PE. A neon lamp would be useful to verify 100% which wires from the ceiling are phase. I drew two pictures.
Yes it is connected by the manufacturer. and you have to do that

However, drilling holes in the ceiling will not be my hobby, but once done and off the top of my head ;p
Thank you very much to everyone who took part in the discussion (as I saw there were more of you). The lamp works and is doing very well, and I also escaped from this skirmish with my life.
You were right with this connection, what and where, so if someone also has a secular problem like me, I confirm - it's ok.
