Permissions to import via GUI


Do you know what role is needed in Couchbase 7.0.3 to be able to use Import from the GUI?
I have a user with Read-Only Admin + Query Insert(bucket::) + Query Update(bucket::) + Query Delete(bucket::) + Data Writer(bucket::) + Manage Scopes(bucket:*) and he can insert via Query, but not via Documents>Import because he receives a message saying “Insufficient permissions to import documents. User must have at least Data Writer on one or more collections, and also the ability to view scopes and collections on that bucket.”
