Как отобразить web страницу в full screen без заголовка и навигационных кнопок?

Question

[Respect and good to all]

Сейчас код такой:

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">


    <WebView
        android:id="@+id/myURL"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:layout_marginStart="1dp"
        android:layout_marginTop="1dp"
        android:layout_marginEnd="1dp"
        android:layout_marginBottom="1dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>

MainActivity.kt

package com.example.myapplication

import android.os.Bundle
import android.webkit.WebView
import android.webkit.WebViewClient
import androidx.appcompat.app.AppCompatActivity


class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        val myWebView: WebView = findViewById(R.id.myURL)
        myWebView.webViewClient = object : WebViewClient () {
            override fun shouldOverrideUrlLoading(
                view: WebView?,
                url: String?
            ): Boolean {
                view?.loadUrl(url!!)
                return true
            }
        }
        myWebView.loadUrl("https://google.com")
        myWebView.settings.javaScriptEnabled=true
        myWebView.settings.allowContentAccess=true
        myWebView.settings.domStorageEnabled=true
        myWebView.settings.useWideViewPort=true
        myWebView.settings.setAppCacheEnabled(true)
    }
}

Если предлагаете в "Fullscreen Activity" развернуть проект то подскажите какой код куда там вставлять, непонятно...
