How to make a gameObject disappear when a mouse hovers and reappear when the mouse leaves?

Greetings Unity Answers, this is my first time asking you.

The situation is:

• There is a cube (gameObject).

• If a mouse hovers over it, the cube disappears.

• If the mouse leaves, the cube reappears.

This is a script I attach to the parent of the gameObject I want to make appear/disappear:

 public class Visibility2 : MonoBehaviour 
     {
         void OnMouseEnter ()
         {
             foreach (Transform child in this.transform)
             {
                 child.gameObject.SetActive (false);
             }
         }
     
         void OnMouseExit ()
         {
             foreach (Transform child in this.transform)
             {
                 child.gameObject.SetActive (true);
             }        
         }
     }

I eventually got the basics right.

i.e Able to use setActive function using keyboard input or mouse button input and attach it to a parent so that (true/false) functions properly.

But the purpose of my question is to find out how to apply an OnMouseEnter/Exit-like input on a setActive function.

There is also a similar script that is also plausible:

 public class Visibility : MonoBehaviour 
 {
     void Update () 
     {
         foreach (Transform child in this.transform)
         {
             if (Input.GetMouseButtonDown(0)) 
             {
                 child.gameObject.SetActive(false);
             }
             else if (Input.GetMouseButtonUp(0)) 
             {
                 child.gameObject.SetActive(true);  
             }
         }
     }
 }

Except that I want to hover with a mouse ,not press a button on a mouse, but as far as I know, there are no substitute Input functions that provides hovering (e.g like OnMouseEnter/OnMouseExit), but maybe this is my best idea I can only get.

It's possible that I miss something or I am doing it wrong, but I am at a dead-end here so if you are able a, if not a full answer, at least a suggestion, that would be great, thanks.
