Move up and down depending on the position of the mouse when it clicks

I have a little dilemma. I'm develop a game and I need to do something that I do not understand. I have an object that moves up and down with this script:

    void FixedUpdate()
{
    if (canClick)
    {
        float moveVertical = Input.GetAxis("Vertical");
        Vector3 movement = new Vector3(0f, moveVertical, 0f);
        Tucan.GetComponent<Rigidbody2D>().velocity = movement * speed;
        Tucan.GetComponent<Rigidbody2D>().position = new Vector3
        (
            -7.5f,
            Mathf.Clamp(Tucan.GetComponent<Rigidbody2D>().position.y, boundary.yMin, boundary.yMax),
            0.0f
        );
    }
}

Now I want to do that when I click Mouse (0), the object moves upwards if Mouse.y> 0 and respectively down if Mouse.y position <0

    private void Update()
{
    Vector3 mouse = Camera.main.ScreenToWorldPoint(Input.mousePosition);
    if (Input.GetMouseButton(0))
    {
        if (mouse.y > 0f)
        {

        }
        else
        {

        }
    }
}

How to do the same code as FixedUpdate, run it in Update, but do the checks. And already moving in dependence on Mouse.y.

Just compare the WorldSpace mouse positions Y to your GameObjects Y

void Update()
{
    Vector3 mouse = Camera.main.ScreenToWorldPoint(Input.mousePosition);
    if (Input.GetMouseButton(0))
    {
        Vector3 movement;
        if (mouse.y > Tucan.transform.position.y)
        {
            movement = Vector3.up;
        }
        else
        {
            movement = Vector3.down;
        }


        Tucan.GetComponent<Rigidbody2D>().velocity = movement * speed;
    }
}

EDIT

Since you wanted a split screen solution

so the screen separates it in two, and when I click up, it moves up and vice versa

void Update()
{
    var mouse = Input.mousePosition;
    mouse.y -= Screen.height / 2;
    if (Input.GetMouseButton(0))
    {
        Vector3 movement;
        if (mouse.y > 0)
        {
            movement = Vector3.up;
        }
        else
        {
            movement = Vector3.down;
        }


        Tucan.GetComponent<Rigidbody2D>().velocity = movement * speed;
    }
}
