Can't do Quaternion.AngleAxis twice.

Question

Hello! I am making a game, in which the camera will rotate around the player with mouse movements. I did this by adding the mousex and mousey movements to a vector2, (mousex being the x, mousey being the y) and then rotating the camera by using Quaternion.AngleAxis. I used two Quaternion.AngleAxis functions, one for the x, and one for the y to rotate it. When I ran the game, only the first Quaternion.AngleAxis in the code would actually rotate the camera, and it would ignore the second. Can I do this some other way? Thanks!

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class camMove : MonoBehaviour {
 
     public GameObject playerBall;
 
     Vector2 mouseLook;
 
     private void Start()
     {
         Cursor.lockState = CursorLockMode.Locked;
     }
 
     void Update ()
     {
         Vector2 mouseVal = new Vector2(Input.GetAxisRaw("Mouse X"), Input.GetAxisRaw("Mouse Y"));
         mouseLook += mouseVal;
         transform.rotation = Quaternion.AngleAxis(mouseLook.x, Vector3.up);
         transform.rotation = Quaternion.AngleAxis(-mouseLook.y, Vector3.right);
         transform.position = playerBall.transform.position;
                  
 
         if (Input.GetKeyDown(KeyCode.Escape))
         {
             Cursor.lockState = CursorLockMode.None;
         }
     }
 }

Typed this up really quick should work I've used this kinda setup before but I didn't test it

 using UnityEngine;
 
 public class CameraLook : MonoBehaviour 
 {
     public float lookSpeed;
 
     public Vector2 horizontalLimiter;
     public Vector2 verticalLimiter;
 
     void Update()
     {
         //Get the mouse input
         float x = Input.GetAxis("Mouse X");
         float y = Input.GetAxis("Mouse Y");
 
         //Rotate the camera around the axis
         Camera.main.transform.RotateAround(transform.position, Vector3.up, x * lookSpeed * Time.deltaTime);
         Camera.main.transform.RotateAround(transform.position, Vector3.right, -y * lookSpeed * Time.deltaTime);
 
         //Limit the rotation THIS IS OPTIONAL REMOVE IF YOU DON'T WANT IT
         Vector3 cameraRotation = Camera.main.transform.eulerAngles;
 
         cameraRotation.x = Mathf.Clamp(cameraRotation.x, horizontalLimiter.x, horizontalLimiter.y);
         cameraRotation.y = Mathf.Clamp(cameraRotation.y, verticalLimiter.x, verticalLimiter.y);
         cameraRotation.z = 0;
 
         Camera.main.transform.eulerAngles = cameraRotation;
     }
 }
