+1. Handle the `lastEvent` [callback type](#subscribecallback) from subscribe callback to detect the end of the event batch.
 1. Subscribe to an additional batch of events with `client.requestAdditionalEvents(...)`. If you don't request additional events at this point, the gRPC subscription will close automatically (default Pub/Sub API behavior).
 
 The code below illustrate how you can achieve event flow control:
