After looking around, make aim/sight reset to normal preset?

I am teaching my partner how to play video games, they are having a hard time keeping their sight parallel to the ground. I have a few ideas how to help them although I know nothing about workshop and don’t know what to do.

have 2 ideas to help them with this although idk which one would help the most.

  1. Allow them to look around like normal, however after they finish with their mouse input, the game automatically corrects on the horizontal axis facing in front of them.

  2. have a their aim very slowly consistently pan up or down depending on if their sight is below or above the horizontal line forcing them to correct the aim mistakes. however have a safe area in the middle where the pan doesn’t happen.

I would like one or both toggleable

how would I even go about creating this?
