Title, I don't have/want to use mods.

I'm guessing there's no switch lite capture card? You could always get a camera and point it at your hands (and thus the game console) while you play. The mods probably won't reject your run for that.

I would say, if you can, get a regular switch to make it easier. if not, try to connect your switch lite to a TV if possible.

The easiest way would be to just point a camera at the screen. It's perfectly allowed and even a former wr used that method of recording.

put a camera on ur head :)

if you have access to a laptop, use the laptop camera and angle it to the switch, it still gives good viewing angles for yourself and the camera to capture the game, just make sure its done on a flat surface, like a coffee table so the laptop doesnt overheat
