prefetch
Whether to automatically prefetch messages when the MessageCollection / NotificationCollection is reconnected. (brought to the foreground or the network connection gets re-established)
If this is set to false, it is strongly recommended to call MessageCollection.loadNext / NotificationCollection.loadNext when the SDK gets reconnected (ConnectionHandler.onReconnectSucceeded) or real-time events might not get added to the collection when received.
