Filebeat: Ingest logs to Datastream

ELK-stack: 7.10
Currently, I'm using filebeat to ingest logs to elasticsearch directly to an index (example: useract-*)

Since 7.9.1, I see a new feature called data-stream.
Question: How can we specify and make filebeat agent to be aware so as where to ingest the logs. I mean how can we enforce the filebeat to ingest logs to particular data-stream instead of traditional index?
