Unity - Instantiate current gameObject while going

There is a problem that I haven't been able to solve for a few days, how do I clone the moving object and make the clone follow the original object letter by letter?There is a problem that I haven't been able to solve for a few days, how do I clone the moving object and make the clone follow the original object letter by letter?

This one main Instantiate

public static Instantiate Instance;


public Rigidbody Ball;

//FixedUpdate ile test et
private void Update()
{
    if (Input.GetMouseButtonDown(0))
    {
        Rigidbody clone;

        clone = Instantiate(Ball, transform.position, transform.rotation);
        clone.velocity = transform.TransformDirection(Vector3.forward * 25);
    }
}

this on clone

public Rigidbody Ball;

public Transform mainPos;

private void Update()
{
    
}
private void OnTriggerExit(Collider other)
{
    if (other.CompareTag("Gate"))
    {
        Rigidbody clone2;

        clone2 = Instantiate(Ball, mainPos.position, mainPos.rotation);
        clone2.transform.parent = gameObject.transform;
    }
}
