Its called App Analytics, and its available in Firebase Performance Monitoring. You can use App Analytics to see how users interact with your app as they move through different screens, including where they get stuck or give up on a particular task. You can also see how much time users spend in each screen of your app, which is useful for identifying bottlenecks and optimizing user flow.
App Analytics works by instrumenting your code so that we know when you enter and exit certain parts of the UI (e.g., views)
