Update: I managed to solve the problem through trial and error. If anyone is interested, check out the video.

I have a question for those who have worked with the skill wheel.
But to ask it, I need to explain what I've done. So:
I added the ability for the knight to learn the Speed Aura skill in the leadership tree.

I also added a display for this perk on the skill wheel.
Now, in the game, the knight can learn it, and when the player clicks on the skill wheel, they see that they can learn it.

The problem is that for other perks, the connections light up when you hover over them (which are needed to learn them). In my case, they obviously don't, because they need to be coded.
Unfortunately, I couldn't figure out what's what in these XDB files.

So, the question is, does anyone know how to edit these XDB files or add new ones?
In general, how can I achieve the effect that the perk I added also highlights when hovered over and displays what is required to learn it, namely, "Leadership + Rally + Leadership 2".
