How can script will auto run on attaching a gameobject in editor?

Question

I have a func with a contextMenu attribute. Every time i have to attach this to a game object afterward i have to click on GenerateSomething. (Lazyness whispering me) is there way to make this auto run attaching on a game object?

 [ContextMenu("GenerateSomething")] //auto run once on attach?
 private void GenerateSomething()
 {
       //spawn something or generate id idk
 }

i found some other solutions to this:

Creating button instead of right click select method

I was thinking this what if i forgot to assign it. which other solution i found is warn yourself

 #if UNITY_EDITOR
     private void OnEnable() {
         if (id == string.Empty)
         {
             Debug.LogError($"{ gameObject.name } gameObject id is not set!");
         }
     }
 #endif

this solution below is not recommended but putting it here

[ExecuteInEditMode]

//your monobehaviour class

this attribute runs your script's onawake enable etc. at editor while not in play mode
