The request includes a filter of the states that the use is interested in. As an example, this allows us to filter only the "Ongoing" transactions. We have also included a filter for the `ProducerId`. This is useful when trying to reverse lookup the `TransactionalId` as we need to do to support the --find-hanging command below.
