I am not of the belief that you have to "unlock" a stone's magical code to get it to work. Its really not complicated.
From a decent 8k or better edge you should be able to use any other finisher either with water or oil alone (whatever medium the stone dictates) or a light slurry.
Very broadly - Razor quality Jnats can seem too keen when used with water alone so using a light slurry will smooth the edge some.
Using Nagura Tenjyou, Mejirou etc creates too many variables. They are for using your base stone when starting at a much lower grit - 1k-3k for example.They are a progression just like synthetics.
When testing a finish stone I always start at 8k synthetic as a baseline. It should improve that edge.

Usually I go to escher from naniva 8k or 10k.
Perhaps my mistake was that I tried Ozuku starting with coarse Botan and ''killed'' the previous sharpenings. Now I will start the process again.

So you went from 8-10k synthetic to about 3k Botan? That would certainly do it.
Avoid variables when testing!

Yes, correct. Can you recommend several types of Jnats to look for (so the set of naguras I have also could be in the business)?

The stone you have may be just fine. You have to find out.
Once you decide it is a good finishing stone you can start introducing naguras.
You can start to use the botan right after bevel set, then the next, and the next etc.
As I have said they are for a progression - not for finishing.
For finishing either a tomo or just base stone slurry if the base stone is acceptable.
I have already mentioned how to do this, the rest is up to you.
