Bug Shake camera effect is not visible through the headset

Hello, I have an issue with a camera effect that I am trying to achieve in my game. I am looking to have a camera screen shake which works all fine and even is working in the editor while I have my headset one.
So the camera view in the editor actually shows the XR Rig camera shaking back and forth but I cannot see this effect appear in the headset. I would be really thankful if someone can help me out with this. Here is the code I have used for the effect:

Code (csharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5.  
6. public class Shake : MonoBehaviour
7. {
8.     public float duration = 1f;
9.     public float delay = 0f;
10.     public bool shake = false;
11.     public AnimationCurve curve;
12.     // Update is called once per frame
13.     void Update()
14.     {
15.         if (shake)
16.         {
17.             shake = false;
18.             StartCoroutine(Shaking());
19.         }
20.     }
21.  
22.     IEnumerator Shaking()
23.     {
24.         Vector3 startPos = transform.localPosition;
25.         float elapsedTime = 0f;
26.         while(elapsedTime < duration)
27.         {
28.             elapsedTime += Time.deltaTime;
29.             float strength = curve.Evaluate(elapsedTime / duration);
30.             transform.localPosition = startPos + Random.insideUnitSphere * strength/10;
31.             yield return null;
32.         }
33.         transform.position = startPos;
34.     }
35.  
36.     void startShake()
37.     {
38.         shake = true;
39.     }
40.  
41.     public void shakeCam(float time)
42.     {
43.         delay = 0f;
44.         duration = time;
45.         Invoke("startShake", 0);
46.     }
47.  
48.     public void delayedShakeCam(float delay, float time)
49.     {
50.         duration = time;
51.         this.delay = delay;
52.         Invoke("startShake", delay);
53.     }
54. }
55.  

 

try moving the camera parent transform, i'd guess camera position is overwritten from XR tracking?

but i wouldn't add camera shake on VR headsets, might be quite uncomfortable..
