I created a new Gmail address for CloudKit testing purposes only, and invited this address to join my team on App Store Connect. I see the new account in the "Developer" part of the Users page.
But when I try to add this new user on the container permission on the CloudKit dashboard, I only see me (my main owner account) and not the developer email address I just created.
Can free developer account added to an Individual Apple Developer Program team access a CloudKit dashboard? I really need this to test my app and see records in the private database (log the new user on the Simulator and a device to test sync is working, etc.).
