Don’t know if it would work on an iPad … but I got a nasty scratch on a Garmin watch & I “fixed” it with a protective cover (it’s still there … but at least you can’t see it )

Toothpaste? https://www.iresq.com/expert-advice/fix-cracked-ipad-screen-toothpaste/

I bet there's an app for it

Put a bandaid on it 😂

Not toothpaste 😜

Put a screen protector on it with some water on the scratch..😅
