docs: // selectEventsForReference allows you to query events for a specific
  // ManagedObjectReference.
  //
  // Event types can be supplied to this function via the eventTypes parameter.
  // This is highly recommended when you expect the list of events to be large,
  // as there is no limit on returned events.
