How to disable plane detection after the plane reaches a certain size

Hello, I'm trying to disable the ARPlaneManger after it has detected planes up to a certain size. However, when I run the code below, the plane manager continues to detect planes past the size of the area I have indicated. Does anyone know how this can be done? Below is my current code.

Code (CSharp):

1. private ARPlaneManager planeManager;
2. private ARPlane plane;
3.  
4. void Awake()
5. {
6.     planeManager = GetComponent<ARPlaneManager>();
7.     plane = GetComponent<ARPlane>();
8. }
9.  
10. void OnEnable()
11. {
12.     plane.boundaryChanged += OnPlaneBoundaryChanged;
13. }
14.  
15. void OnDisable()
16. {
17.     plane.boundaryChanged -= OnPlaneBoundaryChanged;
18. }
19.  
20. void OnPlaneBoundaryChanged(ARPlaneBoundaryChangedEventArgs args)
21. {
22.     float planeArea = plane.size.x * plane.size.y;
23.  
24.     Debug.Log("Current plane area: " + planeArea);
25.  
26.     if (planeArea > 2.5f)
27.     {
28.         planeManager.enabled = false;
29.  
30.         Debug.Log("Plane manager is " + planeManager.enabled);
31.     }
32. }
