region?	The region code to use. This alters the map's behavior based on a given country or territory
auth_referrer_policy?	Maps JS customers can configure HTTP Referrer Restrictions in the Cloud Console to limit which URLs are allowed to use a particular API Key. By default, these restrictions can be configured to allow only certain paths to use an API Key.
