google_maps_api.xml (debug) doesn't appear in android studio

I study Android Studio at last lesson Google Maps Activity for the tutorial. The tutorial videos work on Google_maps_api.xml for define api key but I doesn't even find the it at the Project android section.

My Android Studio Screenshot

I applied the steps of this document. (https://developers.google.com/maps/documentation/android-sdk/start#api-key). I Only skiped to add it to project level build-gradle

buildscript {
    dependencies {
        // ...
        classpath "com.google.android.libraries.mapsplatform.secrets-gradle-plugin:secrets-gradle-plugin:2.0.0"
    }
}

Anymore It works
