Subscription to use bigquery connector

I am currently using Google Workspace, and it includes the AppSheet core subscription. However, the database is limited to the AppSheet database or the Google Sheet connector. Is there any way for Google Workspace subscribers to use the BigQuery connector? I have already contacted sales, but I have not received a response. It does not make sense to subscribe to both Google Workspace and Enterprise Standard simultaneously just to use the BigQuery database.

Thank you.

When using databases like BigQuery, SQL, MySQL etc. with deployed apps, you need to have AppSheet Enterprise subscription. Unfortunately Core is not enough.

Excuse me:
I am also using Google Workspace, and it includes the AppSheet core subscription. If I want to use a SQL database, I need all users to upgrade to AppSheet Enterprise, or only the program owners. (Other users use core)

All users unfortunately sir.
