Just the flap and the gasket it seats into, wipe it down with a wet paper towel, see if it still does it
You can also try adjusting the linkage (chain length) sometimes a flap “floats down” slowly because there’s still some water. And that might be causing issues.
Anytime you fuck with a toilet, you want to try the least invasive methods first and work your way up.
Shit can get out of hand quickly and you may end up replacing everything and still experiencing the same issue.
