I have successfully accessed /screening/v3/cases and received results; however, when passing a groupId, it seems that name is the only field available for specifying search criteria. How can I configure additional search parameters—such as country? It appears that customFields can be set (which seems linked to templates), yet I cannot find a parameter in /cases to specify a template. I would also like to know how to configure (create) a template and how to use it within cases.
