It would be great if we could query the list of collaborators and the bases for which they have access via the API or download it from the portal.
The current UI makes it very tedious to audit the current user base.
My current work around is to copy the payload of workspaceSettings.json which arrives when navigating to the airtable.com/wspXXXXXXXXX/workspace/billing. The key billableUserBreakdown appears to have all the data I need. Even just being able to download that file using my API key would be a huge benefit.
