How to enable disabled gameobject in unity

I want to disable a GameObject, for achieving this I have written a code like this:

GameObject go;
go = GameObject.FindWithTag("MainCamera");
Destroy(go);

Then I am struggling to enable that disabled GameObject.

Could anyone help me on this regard?

When calling Destroy, you .... destroy the gameobject, you don't disable it. Instead, use SetActive.

Moreover, avoid using functions like FindXXX, especially multiple times. Add a reference in the inspector instead

 // Drag & Drop the gameobject in the inspector
 public GameObject targetGameObject ;

 public void DisableGameObject()
 {
      targetGameObject.SetActive( false ) ;
 }

 public void EnableGameObject()
 {
      targetGameObject.SetActive( true ) ;
 }

 public void ToggleGameObject()
 {
      if( targetGameObject.activeSelf )
           DisableGameObject() ;
      else
           EnableGameObject();
 }

Else, find the object once, either in the start function or when you try to disable the gameobject. Keeop in mind that FindXXX functions can't find disabled gameobject (most of the time)

 // Drag & Drop the gameobject in the inspector
 private GameObject targetGameObject ;

 public void DisableGameObject()
 {
      if( targetGameObject == null )
             targetGameObject = GameObject.FindWithTag("MainCamera");
      if( targetGameObject != null )
           targetGameObject.SetActive( false ) ;
 }

 public void EnableGameObject()
 {
      if( targetGameObject != null )
           targetGameObject.SetActive( true ) ;
 }

 public void ToggleGameObject()
 {
      if( targetGameObject == null )
          targetGameObject = GameObject.FindWithTag("MainCamera");

      if( targetGameObject == null )
          return ;

      if( targetGameObject.activeSelf )
           DisableGameObject() ;
      else
           EnableGameObject();
 }

Duplicate question But .....

https://docs.unity3d.com/ScriptReference/GameObject.SetActive.html

Tip:

go.SetActive(!go.activeInHierarchy); // Toggle gameobject.

go = GameObject.FindWithTag("TADA") // Better
