Home button sticks and rotates

A1489 iPad button gets physically stuck, as in no tactile response is felt. It seems to have some rotation, and only clicks down when the square symbol is not rotated too far out of spec. I have tried cleaning it with rubbing alcohol per instructions found online, but I’m not turning up the right search terms as I get false positives with screen rotation issues.

What would I look for to fix it when I open it up? Ideally without buying new parts that cost more than a newer device. Thank you.
