What company data can I verify in Brunei?

Does the API return beneficial ownership (UBO) data for Brunei companies?
The API resolves the controlling parties, shareholders, and beneficial owners for Brunei companies and exposes them as a recursive ownership org-chart (GET /v2/Companies/{caseCommonId}/org-chart), tracing control through holding companies to the individual beneficial owners. The depth available depends on what the One Common Portal discloses. See the UBO API.
