Tile a sprite for a background

Unity Engine
1

I want to repeat a sprite for a background. I cant use the material tilling method because it seem to come in contradiction with 2ddl . Anyhow, I know someone post this wonderfull code thanks to ash blue

the problem is it only tile in vertical and I am not sure to know how to do so that t tile both verticxaly and horizontally. I tried a for method inside a for method or adding this script

    void Start () {
       
        sprite = GetComponent<SpriteRenderer>();
        Vector2 spriteSize = new Vector2(sprite.bounds.size.x / transform.localScale.x, sprite.bounds.size.y / transform.localScale.y);

        GameObject child;
        for (int i = 1, l = (int)Mathf.Round(sprite.bounds.size.x); i < l; i++) {
            child = Instantiate(Tile) as GameObject;
            child.transform.position = transform.position - (new Vector3(spriteSize.x, 0, 0) * i);
            child.transform.parent = transform;
        }

        Tile.transform.parent = transform;

        // Disable the currently existing sprite component since its now a repeated image
        sprite.enabled = false;

    }
   
    // Update is called once per frame
    void Update () {
       
    }
}

who basicallu repeat the object that was repeating, anywaym both solution does not work and I am not that familiair with the for method

If you use an Image instead of a Sprite (Game Object → UI → Image) you can set the image type to “Tiled” and then you don’t need to write any code.

I really need it to be a sprite because of the way 2ddl work,
