Hi Kaniz. 

We are utilizing the latest driver, and we are explicitly not providing USE SCHEMA on this entry.

Our permission architecture separates the type of access you have, and the domain in which data relies. This means that certain users will have access to all Foreign Catalogs, however might not have access to any schemas in it, as that data resides in a domain you do not have access to. This is essentially in following the Medallion Architecture. This is not a problem anywhere else, and results in the fact that our normal data-users can utilize Excel and spark without issue, however our data scientists cannot, as they have access to foreign catalogs.
