Switch Lite and "secondary" skills

So with the PC I’ve seen on icyveins that the first mouse button is the “primary” skill and the second mouse button is the “secondary” skill. Couple with buffs like “adds 400% to secondary skills damage” is that the actual slot it’s in, or the actual secondary skill category? Because as I look at the controls on my switch lite, there’s not really a specific button mapped to a specific primary or secondary like what appears to be in the PC version (unless I’ve misunderstood something).
Hoping this makes sense thanks.

It’s the skill the item is talking about, primary skills are the resource generator regardless of which button it’s on. Same goes for secondary, they are secondary skills regardless of the button

Perfect thank you! And an additional bit of text since I can’t post less than 20 :wink:
