can not resolve method add for Fragment Transaction

I was just upgrading old android project and stuck at below code :

 FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
 transaction.add(R.id.instructional_tutorial_video_youtube_view, youTubePlayerFragment).commit();
 return view;

Here, It giving me a compile time error : can not resolve method add(int, com.google.android.youtube.player.YouTubePlayerSupportFragment)

The Xml file named R.id.instructional_tutorial_video_youtube_view is as below :

   <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@ id/test"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.brian.skyazul.fragment.InstructionTutorialVideoViewFragment">
    <include
        android:id="@ id/video_topbar"
        layout="@layout/topbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <com.google.android.youtube.player.YouTubePlayerView
        android:id="@ id/instructional_tutorial_video_youtube_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@ id/video_topbar"
        android:layout_centerInParent="true"
        android:layout_gravity="center" />
</RelativeLayout>

What might causing the issue? Or Is there any alternative to resolve this? thanks.

fragment tag instead of YoutubePlayerView tag

<fragment
android:id="@ id/youtubeFragment"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:name="com.google.android.youtube.player.YouTubePlayerFragment">

I haven't used before, I hope playerview it's in fragment itself.

In your fragment class

val youtubeFragment =
        childFragmentManager.findFragmentById(R.id.youtubeFragment) as YouTubePlayerFragment
    youtubeFragment.initialize("YOUR API KEY",
        object : OnInitializedListener() {
            fun onInitializationSuccess(
                provider: YouTubePlayer.Provider?,
                youTubePlayer: YouTubePlayer, b: Boolean
            ) {
                // do any work here to cue video, play video, etc.    
                youTubePlayer.cueVideo("")
            }

            fun onInitializationFailure(
                provider: YouTubePlayer.Provider?,
                youTubeInitializationResult: YouTubeInitializationResult?
            ) {
            }
        })

Instead of using this, I just used :

implementation 'com.pierfrancescosoffritti.androidyoutubeplayer:core:11.0.1'

<com.pierfrancescosoffritti.androidyoutubeplayer.core.player.views.YouTubePlayerView
    android:id="@ id/instructional_tutorial_video_youtube_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@ id/video_topbar"
    android:layout_centerInParent="true"
    android:layout_gravity="center" />

and inside Java :

 YouTubePlayerView youTubePlayerView = findViewById(R.id.instructional_tutorial_video_youtube_view);
    youTubePlayerView.addYouTubePlayerListener(new AbstractYouTubePlayerListener() {
        @Override
        public void onReady(@NonNull YouTubePlayer youTubePlayer) {
            String videoId = youtubeVideoURL;//"S0Q4gqBUs7c";
            youTubePlayer.loadVideo(videoId, 0);
        }
    });

and it worked like a charm!
