How to remove point clouds in Arkit?

After gettting the plane detected we remove the debugplane prefab that is the blue coloured rectangles. Similarly how to remove the point clouds that is coming once the plane is detected or after I place a 3d model on touch the plane(using UnityHitTest).

My objective is to hide planes and point clouds after arworldmap is loaded.Any idea?

 using UnityEngine;
 using UnityEngine.XR.iOS;
  
 public class PointCloudParticleExample : MonoBehaviour
 {
     public ParticleSystem pointCloudParticlePrefab;
     public int maxPointsToShow;
     public float particleSize = 1.0f;
     Vector3[] m_PointCloudData;
     bool frameUpdated = false;
     ParticleSystem currentPS;
     ParticleSystem.Particle [] particles;
     //added
     int loadcheck=0;
  
  
     //For creating instance of class
     public static PointCloudParticleExample pointinstance;
  
     // Use this for initialization
     void Start ()
     {
         UnityARSessionNativeInterface.ARFrameUpdatedEvent += ARFrameUpdated;
         WorldMapManager.offevent += particlesoff;//Added event
         currentPS = Instantiate (pointCloudParticlePrefab);
         m_PointCloudData = null;
         frameUpdated = false;
         pointinstance = this;
     }
    
     public void ARFrameUpdated(UnityARCamera camera)
     {
         if (camera.pointCloud != null)
         {
            m_PointCloudData = camera.pointCloud.Points;
         }
         frameUpdated = true;
     }
  
     // Update is called once per frame
     void Update ()
     {
      
         if (frameUpdated)
         {
             if (m_PointCloudData != null && m_PointCloudData.Length > 0 && maxPointsToShow > 0 && loadcheck == 0)
             {
                 int numParticles = Mathf.Min (m_PointCloudData.Length, maxPointsToShow);
                 ParticleSystem.Particle[] particles = new ParticleSystem.Particle[numParticles];
                 int index = 0;
                 foreach (Vector3 currentPoint in m_PointCloudData)

                     index++;
                     Debug.Log("Points set to 0 called");
                     if (index >= numParticles) break;
                 }
                 currentPS.SetParticles (particles, numParticles);
