Rotate player to screen pos

Hey, this is for a top down game.

I want the player to always face the point where the mouse is (without use of raycast).

Got the code working for a controller but not for mouse:

     private void RotatePlayer() {
         Vector2 mousePos = Camera.main.ScreenToViewport(Input.MousePosition);
         float angle = Mathf.Atan2(mousePos.x, mousePos.y) * Mathf.Rad2Deg;
         Quaternion desiredRot = Quaternion.AngleAxis(angle, transform.up);
         rb.rotation = Quaternion.Lerp(rb.rotation, desiredRot, rotationSpeed * Time.fixedDeltaTime);
     }

Actually I think the calculation of the angle is wrong. How can I correctly get the angle of the mouse and an object in 3D space (viewport)?

Any suggestions? Greets
