Wikitude

I am trying to use WikitudeCamera and Natcorder to record the device screen to be able to record the AR experience as well. I am stuck and would appreciate some help here.

NatCorder has just one article but I am not able to understand how to connect it with Wikitude - https://medium.com/@olokobayusuf/natcorder-unity-recording-made-easy-f0fdee0b5055

Moreover I am also facing trouble with taking screenshot and saving it in the device's gallery. It seems like it is not saving at all as I am unable to view the screenshot in the gallery. I tried using this plugin - https://github.com/yasirkula/UnityNativeCamera

this is what i tried

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Wikitude;
using NatCorderU;
using NatCorderU.Core.Clocks;
using NatCorderU.Core;
using System;
using System.IO;

public class CameraControllerScript : MonoBehaviour
{
   
    private Texture2D _cameraFeed;
    public bool takingScreenshot = false;
    // Start is called before the first frame update
    void Start()
    {
        NativeCamera.Permission myPermission = NativeCamera.CheckPermission();
        NativeCamera.RequestPermission();
        if(myPermission.Equals(NativeCamera.Permission.Denied)){
            NativeCamera.RequestPermission();
        }
    }

    // Update is called once per frame
    void Update()
    {

    }

    public void TakePicture()
    {
        StartCoroutine(CaptureScreenshot());

    }

    private IEnumerator CaptureScreenshot(){
        takingScreenshot = true;
		yield return new WaitForEndOfFrame ();
		
        _cameraFeed = new Texture2D (Screen.width, Screen.height, TextureFormat.RGB24,false);
		_cameraFeed.ReadPixels(new Rect(0,0,Screen.width,Screen.height),0,0);
        _cameraFeed.Apply();
        
        string path = string.Format("{0}_Capture{1}_{2}.png",Application.productName,"{0}",System.DateTime.Now.ToString("yyyy-MM-dd_HH-mm-ss"));
        NativeGallery.SaveImageToGallery(path,Application.productName + "Captures",path);
        takingScreenshot = false;
    }
}
