Hi Manuel,
Thank you for reaching out.
However, my apologies as I would not be able to comment further regarding the availability of metrics in BigQuery as a result of your integration. Our team provides support only for AdWords API / Google Ads API specific concerns only.
That being said, you may reach out to the product experts via the Google Ads Help Community forum as they may be able to provide more guidance regarding this matter. You may also reach out to the BigQuery team directly for additional assistance.
I hope this helps.
Best regards,
Peter
Google Ads API Team
