Question How to make third person cinemachine camera rotate up/down with vertical mouse position

Hello I am working on a third person game and I can't figure out how to make the third person camera from cinemachine angle with the mouse Y position from the new input system .
How do i change my camera euler angle ?

Code (CSharp):

1.     private void TurnWithMouse()
2.     {
3.         xRotation -= mousePosition.y;
4.         xRotation = Mathf.Clamp(xRotation, -30f, 50f);
5.         Vector3 targetRotation = head.transform.eulerAngles;
6.         targetRotation.x = xRotation;
7.         head.eulerAngles = targetRotation;
8.         playerCamera.eulerAngles = targetRotation;
9.   /*       Debug.Log(playerCamera.eulerAngles);*/
10.         transform.Rotate(Vector3.up, mousePosition.x * Time.deltaTime * mouseSensitivityX);
11.     }

 

Thank you sir!!
