[FR]: Observe Screen View Events

### Description

1. I'd like to observe when the Firebase fires a screen view event so that i can work with this event further.
2. I could not find any way how to observe/get a callback when Firebase triggers such this event.
3. Add a delegate to the Analytics. Optionally, is there an option to use a Firebase API to fetch all screen events for a specific uid?

### API Proposal

_No response_

### Firebase Product(s)
