How to make ball bounce off screen boundaries?

Hello I have a script that keeps all my objects within the sides of the screen perfectly

public SpriteRenderer sprRnd:

void Update ()
{
    Vector3 leftBottom = Camera.main.ViewportToWorldPoint(Vector3.zero);
    Vector3 rightTop = Camera.main.ViewportToWorldPoint(new Vector3(1, 1, 0)); 

float leftLimit = leftBottom.x;
float rightLimit = rightTop.x;
Vector3 extents = sprRnd.bounds.extents;

Vector3 pos = transform.position;
pos.x = Mathf.Clamp(pos.x, leftLimit + extents.x, rightLimit - extents.x);

transform.position = pos;

And I’m trying to get the ball to bounce off the screen boundaries I added box Collider2D rigidbody2D & a bounce material to the ball & ball force but when it hits the edge it does bounce off. I did create quads with box Colliders & it worked but I would prefer to use the screen as boundaries is this possible?

You could still use box colliders, just scale and move them to the size of the screen!
