how to make mongocxx cursor return batch results

If my DB stores lots of documents, and the find() will only return a batch size of documents, how can I use mongocxx::cursor to move to next batch? I didn't find any examples, can someone give me some suggestions or should I switch to mongoc driver?

The cursor will continue to fetch batches as you advance it. You don't need to do anything special.

Please see/run this example:
