I'm looking to report on the outcome of a Firebase A/B test using Google Analytics / BigQuery tables.
To do this I need to identify the test group each user was in.
The Firebase documentation (https://firebase.google.com/docs/ab-testing/ab-concepts) suggests experiment and variant memberships are stored as user properties on every GA event in the normal GA event tables.
However, I can't find this information associated with GA events in the GA interface or BQ clickstream tables - I can only see it in the Firebase tables.
Where should I be looking? I've checked the Event Action, Event Category, Event Label etc. dimensions.
