6. I want to connect my GA4 account and another data source from BigQuery as goals for my experiments. As I understand, GrowthBook recognizes the GA BigQuery schema, and I can automatically set goals like pageviews, conversions, average time spent on the page, etc.
But what is the best-aggregated data structure in BigQuery for measuring goals in GrowthBook for my another data source? Do you have some examples how this should looks in table?
