How to make OnCollisionEnter2D work multiple times?

Question

I have a character and if he touches a certain zone, then a certain object appears, and if he does not touch,
then the object becomes invisible, but there is a problem when I enter a certain zone, the object appears, but when I leave the zone, the object does not become invisible, how to solve?
