Prefab UI Image is invisible when Instantiate

Unity Engine

I want to generate grid on canvas, but i don’t want fill canvas so i spawn objects inside Panel, but even without Panel and adding Images to Canvas images are still invisible
I have Canvas which have Panel as children which contains my script to spawn and GridLayoutGroup, I want to Instantiate prefab which contains UI Image but when making it by script my Images are invisible

I have this script attached to my Panel

for(int x =0;x<width;x++){
            for(int y=0;y<height;y++){
                GameObject newTile = Instantiate(_tilePreset,gameObject.transform.position,Quaternion.identity);

                gridMapGameObjects[x,y]=newTile;
                newTile.transform.SetParent(gameObject.transform);
            }
        }

It only works when adding manually every image to my Panel.
It worked with SpriteRenderer but sprites are over UI elements

Okay nvm i just figured out that scale of Tile on RectTransform was too big
