browse external GCP bucket?

There are various doc pages on accessing external data, such as:

• https://support.terra.bio/hc/en-us/articles/360042670651-Best-practices-for-sharing-and-protecting-data-resources#h_ddbd1c0d-a9f5-46c2-bcd9-5b175dbb4473
• https://support.terra.bio/hc/en-us/articles/8346852411035-How-to-access-external-Google-Cloud-resources-
• https://support.terra.bio/hc/en-us/articles/360024617851

...but the docs discuss granting access (e.g., changing bucket permissions on the GCP console), and do not show how one then views/browses the external bucket data in Terra. I don't see any docs on browsing buckets that are external from the Workspace bucket.

I'm assuming that external buckets can be browsed directly in Terra (assuming correct permissions), given that Terra is supposed to make data analysis for biologists easy, and file browsing/access is a fundamental feature.

It would be great to have some clear docs on this topic (e.g., a doc page with the title "how to browse data in an external bucket?).
