How to turn off switching between apps with finger swiping?

I play a lot of rythm games. Sometimes while playing, i have to use more than 3 fingers, and sometimes when i use 4 fingers, when i move them my app switches and i lose my progress.

I know that there's this function of switching between apps while swiping with 4+ fingers, but i don't know how to turn it off. I really want to turn it off.

I use an iPad with iPadOs 16.5.1 version
