How can I access the childs of a sprite on multiple mode?

What I'm doing is trying to access the array of sprites under the "root texture" using an editor script

     //EDITOR BUTTON TO INSTANTIATE SEVERAL SPRITES ON SCREEN AT ONCE
     [MenuItem ("GameObject/Create Other/InstSprites")]
 
     static void InstSprites() 
     {
         //IF THERE IS SOMETHING SELECTED ON INSPECTOR/PROJECT
         if (Selection.activeObject != null)
         {
             Sprite[] textures = //WHAT SHOULD I WRITE HERE TO IMPORT THE ARRAY OF SPRITES? 
                 //THIS SHOULD BE AN OPTION, BUT IT DOENS'T WORK AS I EXPECTED...
                 //                UnityEngine.Object[] allSprites = Selection.objects;
             string[] names = new string[textures.Length];
             
             for(int ii=0; ii< names.Length; ii++) {
                 names[ii] = textures[ii].name;
                 Debug.Log(names[ii]);
                 GameObject ssprite = new GameObject();
                 ssprite.name = names[ii];
                 ssprite.AddComponent<SpriteRenderer>();
                 ssprite.GetComponent<SpriteRenderer>().sprite = Sprite.Create(textures[ii].texture, textures[ii].textureRect, Vector2.zero , 100f);
             }
 }
 }

That's it. Any Insights?

Thank you.
