We connected Google Analytics 4 (GA4) to BigQuery.

We a looking for someone who has experience connecting GA4 with BQ and working with data from GA4. There is a screenshot in the files names "analytics" - we need to get this data in BigQuery.

Now we are trying to create a table with the data as we see it in GA4: users, sessions, engage sessions, Average engagement time per session, Engaged sessions per user by sourse/medium and date.
