Can someone help me configure my controllers please?

Quest 2

I am rubbish a video games always have been, but I’m okay at beatsaber I can even do some easy songs on expert but, my accuracy sucks. Please bear in mind that I am old and know nothing about mods, or video games in general. I changed the controller settings and that improved any blocks needing side slices but the ones right in front of have lost some points. I see lots of YouTube’s about controller setting but they all use some software the quest doesn’t seem to have. Thank you!
