Help connecting TechKen Switch Pro Controller

[MarioLuigiNabbitTrio]

So I was trying to use my TechKen Pro Controller but it doesn't seem to be working when I try to connect it like I connected my normal Pro Controller, does anyone have a solution to this?

I don't see one else trying this on PC when I do a search, so I can only guess it's weird and doesn't work like a normal pro controller.
