Download the google-services.json file from Firebase Console (for whatever Firebase project you have or want to integrate the test-app) and store it under the current directory.

Note: The Package name for your app created on the Firebase Console (for which the google-services.json is downloaded) must match the applicationId declared in the test-app/test-app.gradle.kts for the app to link to Firebase.

Run the test app directly from Android Studio by selecting and running the firebase-sessions.test-app run configuration.
