How to change mouse cursor with multiple textures based on tag

If i move my mouse to an object with tag , the mouse cursor should change to a texture and if mouse is not over any specified tagged object it should have a default cursor. By writing the below code, my mouse is stuck in the default cursor even if i move it to a tagged object.

  public class Hover : MonoBehaviour {
     
         public Texture2D defaultTexture;
         public Texture2D attackTexture;
         public Texture2D pickupTexture;
         public Texture2D interactTexture;
     
         public CursorMode curMode = CursorMode.Auto;
         public Vector2 hotSpot = Vector2.zero;
     
         // Use this for initialization
         void Start () {
             Cursor.SetCursor(defaultTexture, hotSpot, curMode);
         }
         
         // Update is called once per frame
         void Update () {
             
         }
     
         public void OnMouseEnter()
         {
             if (gameObject.tag == "Enemy")
             {
                 Cursor.SetCursor(attackTexture, hotSpot, curMode);
             }
     
         }
         public void OnMouseExit()
         {
             Cursor.SetCursor(defaultTexture, hotSpot, curMode);
         }
     }

Any help would be appreciated ^_^
