rotateAround pivots at unexpected point

Question

My intention is to have the camera orbit the player, however it spins in place instead of moving around the player at a fixed distance. Have I misunderstood something? targetTransform is the player transform;

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class FollowTarget : MonoBehaviour
 {
 
     public Transform targetTransform;
     public float cameraOffset;
     [Range(0.01f, 1)]
     public float smoothFactor = 0.5f;
 
     void Start()
     {
         transform.position = GetCameraOffset();
         transform.LookAt(targetTransform);
     }
 
     void LateUpdate()
     {
         // Follow Player
         transform.position = Vector3.Slerp(transform.position, GetCameraOffset(), smoothFactor);
 
         // Rotate around Player if mouse button is held down
         if (Input.GetMouseButton(0))
         {
             transform.RotateAround(targetTransform.position, Vector3.up, Input.GetAxis("Mouse X") * Time.deltaTime * -180);
             transform.RotateAround(targetTransform.position, transform.right, Input.GetAxis("Mouse Y") * Time.deltaTime * 180);
             return;
         }
     }
 
     Vector3 GetCameraOffset()
     {
         return new Vector3(cameraOffset, 0, 0) + targetTransform.position;
     }
 }

You're setting the transform.position at a fixed offset (or rather, you're lerping it to that fixed offset, specifically on the line following // Follow Player) each frame, so no matter where RotateAround wants to put your camera, it'll inevitably be returned to the original offset the next frame. You'll have to find a different way to tell the camera to follow the player if you want it to be able to orbit the player, otherwise you'll always be stuck around new Vector3(cameraOffset, 0, 0) + targetTransform.position.

Thanks, of course it was that haha. I thought I had tried commenting it out at some point but I guess I had not.
