Grid Layout group with prefabs aren't working

Unity Engine
1

Im adding a bunch of prefabs to a grid Layout Group but they arent organising and just sit on the default location.

This is the code I have, as you can see Ive tried a few different ideas that have been suggested.

Any ideas?

          var bucket = Instantiate(BucketPrefab, bucketPosition, quaternion.identity);
          

            bucket.transform.SetParent(BucketGrid.transform,false);
            bucket.transform.localScale = new Vector3( 1.0f, 1.0f, 1.0f );
            bucket.transform.localPosition = Vector3.zero;

You’re referring to the UI GridLayoutGroup? That isn’t 2D, it’s UI here.
