Need help with setting up bottom buttons to be invisible

[ShelbyShadow]

How do I get the buttons on bottom

 be invisible. So they don't interfere with games.

Install Good Lock + NavStar. Then toggle the "show and hide button" option.

Good Lock's NavStar is a good manager for this, but first see if One UI's settings will do. Go to phone Settings > Display > Navigation Bar, and choose gestures instead of buttons.
