Directly refrencing a 9-spliced Sprite

I scoured the googles looking for some help, but failed to find a good way to solve this issue, but i happened to make something work. However id like to know if there is a better way to handle getting a specific spliced image.. for example, I have a file that has 3 different images Tab_Window, Tab_Active, Tab_Inactive all on the same sprite sheet. Each sprite has been 9 spliced.

I know how to do this within Unity Editor, but im trying to make a mod for another unity game outside of unity. like i said though .. i did manage to figure out a way to do it, but is there a better way than this

  Image _backgroundImage = _canvasPanel.gameObject.AddComponent<Image>();
 _backgroundImage.type = Image.Type.Sliced;
 _backgroundImage.sprite = GetSpecificSprite("Tab_Inactive", "Images/Tabs");
 
 
 public static Sprite GetSpecificSprite(string spriteName, string resourceLocation )
     {
         Sprite[] spritesheet = Resources.LoadAll<Sprite>($"{resourceLocation}");
         if(spritesheet != null)
         {
             foreach (Sprite sprite in spritesheet)
             {
                 if (sprite.name == $"{spriteName}")
                 {
                     return sprite;
                 }
             }
         }
      Debug.Log($"Sprite {spriteName} not found in {resourceLocation}");

      //dummy texture to prevent null
     Texture2D texture = new Texture2D(0, 0);
     return Sprite.Create(texture, new Rect(0, 0, texture.width, texture.height), Vector2.zero);
     }
