Currently, if you link GA4 and BigQuery, Google only provides data from the day you linked it and won’t backfill historical data prior to that. Therefore, if you want to access the data from before May 6th, you would need to find another method. Writing a Python script could potentially solve this problem. However, it would depend on your coding skill, the complexity of the script and whether GA4 and BigQuery have the APIs needed for your script. Using a third party tool like Fivetran or Supermetrics is also an option, as they provide functionalities to backfill historical data by exporting it from Google Analytics to BigQuery.
