Rotating a prefab for Vertical Planes

Hi , I've tried every possible combination of rotating my indicator based on the alignment of the plane but can not seem to get it vertical even in the slightest.

Code (CSharp):

1.            AnchorIndicator.SetActive(true);
2.             var pose = planeHits[0].pose;
3.  
4.             var alignment = arSessionOrigin.GetComponent<ARPlaneManager>().GetPlane(planeHits[0].trackableId).alignment;
5.             Debug.Log("Alignment = " + alignment);
6.  
7.             var xRotaion = alignment == UnityEngine.XR.ARSubsystems.PlaneAlignment.Vertical ? -90 : 0;
8.            
9.             var cameraForward = Camera.main.transform.forward;
10.             var cameraBearing = new Vector3(cameraForward.x  + xRotaion , 0, cameraForward.z ).normalized;
11.  
12.             pose.rotation = Quaternion.LookRotation(cameraBearing);
13.          
14.             AnchorIndicator.transform.SetPositionAndRotation(pose.position, pose.rotation);
15.         }

Any tips in the right direction would be greatly appreciated.
