Get All GameObject in Prefab Mode

Question

I have a custom script that Inherit from TextMeshProUGUI and now I want to convert all of my GameObjects UI that have TextMeshProUGUI into my custom script. I have created a MenuItem and the logic for changing it. It works wonderfully. The problem is that, I wanted to be able to change the TMPUGUI in prefabs as well, but my current code only gets the GameObjects that is in the current scene. How do I / Is there a function to get all the GameObjects in Prefab Scene mode? Is there a way to detect if I'm currently in Normal Scene or in Prefab Scene mode? because I want to use 1 Menu Item that can be used both in Normal Scene and Prefab Scene mode if the way to get the GameObjects is different between modes. Thank you.

     [MenuItem("Tools/Migrate TMPUGUI to TMPLanguage")]
     public static void MigrateTMPToTMPLang()
     {
         TextMeshProUGUI[] TMPs = GameObject.FindObjectsOfType<TextMeshProUGUI>();
 
         ...
     }

Alright, after all this time, I finally found it. PrefabStageutility.GetCurrentPrefabStage(). It's using UnityEditor.Experimental.SceneManagement;

     TextMeshProUGUI[] TMPs = new TextMeshProUGUI[0];
     if (PrefabStageUtility.GetCurrentPrefabStage() != null) //In Prefab Mode
         TMPs = PrefabStageUtility.GetCurrentPrefabStage().FindComponentsOfType<TextMeshProUGUI>();
     else if (Selection.activeGameObject != null) //For changing selected only (include child). Works for prefab as well (no need to open the prefab).
         TMPs = Selection.activeGameObject.GetComponentsInChildren<TextMeshProUGUI>(); //Could use Selection.gameobjects for multiple selection, probs change TMPs to List
     else //In Scene Mode not selecting anything
         TMPs = GameObject.FindObjectsOfType<TextMeshProUGUI>();

Hello, you can not find gameobect if it not exist in the scene, you need to instantiate first.

Reference : https://docs.unity3d.com/Manual/InstantiatingPrefabs.html
