      BigQuery exports that are created with Security Command Center API V2 and

      included in the resource name of a BigQuery export, you must specify it
      when referencing the export. For example, the following BigQuery export
      name has `location=eu`:
      `organizations/123/locations/eu/bigQueryExports/test-bq-export`.
