Resolved Disable and re-enable image tracking ARKit

Is there a way to disable and re-enable tracking for images in ARKit? From the older version, this was the solution. But in the newer versions have removed UnityARSessionNativeInterface script.

Code (CSharp):

1.  void Start ()
2.      {
3.          m_session = UnityARSessionNativeInterface.GetARSessionNativeInterface();
4.      }
5. void AddImageAnchor(ARImageAnchor arImageAnchor)
6.      {
7.              //at the bottom of this function
8.              StartCoroutine(RemoveAnchorCoroutine(arImageAnchor));
9.        
10.      }
11.     IEnumerator RemoveAnchorCoroutine(ARImageAnchor anchor)
12.      {
13.          yield return new WaitForSeconds(3.0f);
14.         //doesn't have to be in a coroutine, but for my uses it is
15.          m_session.RemoveUserAnchor(anchor.identifier);
16.      }
