Hey all, I'm using BigQuery as a Destination, and trying to add GCS Staging. The docs on that page mention the following permissions for the bucket, but I don't see that anywhere in the Permissions tab. I have a service account already (and can specify that as a principal). Am I missing something obvious?

You need to have this permissions:

GCP has Roles and Permissions, the first screenshot you sent shows the exact permissions Airbyte recommends, the second screenshot and Marcos reply refers to Roles that should include these permissions for you
