How do you scroll through variant lobby games on PC

I know it sounds dumb, but  for some reason I just can't scroll through the games in the variants lobby. It works on chromebook, but not on my PC. Is there a setting option for this that I just didn't know? Or is it a keybind?

I use mouse to scroll

use 2 fingers and scroll

mouse scrolling doesnt work for me, and i dont have touchscreen

got to the here

click custom then it will look like this

i meant variants as in 4 player chess, etc.

then click on standard

and then you change the type of chess game

does that work

i meant like here

i cant scroll through the games here for some weird reason

Use the bar on the right

i dont see it
