From Unity android app open setting panel within custom canvas view

Question

I would like to open Unity Android application from the setting panel within the custom canvas view.

Can I get a code snippet to bring it within canvas view rather than opening over the whole window?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using System.Runtime.InteropServices;
using System.IO;
using System;


public class GetSetting : MonoBehaviour
{
    void Start()
    {
#if UNITY_ANDROID

        string bundleId = "com.android.settings";
        AndroidJavaClass up = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
        AndroidJavaObject ca = up.GetStatic<AndroidJavaObject>("currentActivity");

        AndroidJavaObject packageManager = ca.Call<AndroidJavaObject>("getPackageManager");

        //if the app is installed, no errors. Else, doesn't get past next line
        AndroidJavaObject launchIntent = packageManager.Call<AndroidJavaObject>("getLaunchIntentForPackage", bundleId);
        launchIntent.Call<AndroidJavaObject>("addCategory", "android.intent.category.MAIN");
        launchIntent.Call<AndroidJavaObject>("addCategory", "android.intent.category.HOME");
        launchIntent.Call<AndroidJavaObject>("setFlags", 0x10000000);
        ca.Call("startActivity", launchIntent);

        up.Dispose();
        ca.Dispose();
        packageManager.Dispose();
        launchIntent.Dispose();
#else
        Debug.Log("No Toast setup for this platform.");
#endif
    }
}
