Between this: screen_class example from GA's sample project
And this: firebase_screen example from GA's sample project
And this: screen_id example from GA's sample project
What are use cases for each of them? Is firebase_screen the same as screen_class (i.e. screen name), but overrides it? I can't find any documentation for this except this, which doesn't make it clear, feel free to share what you've found and where. Thanks!
