Using streams.publish procedure is there a way to publish events with key in Kafka topic?

[kavitakjava]

As we know we can publish events with key in Kafka topic
e.g.
kafka-console-producer --topic key-value-topic --broker-list localhost:9092 --property "parse.key=true"
--property "key.separator=:"
key1:{value1}
key2:{value2}
key3:{value3}

Is there a way to publish events with key using streams.publish ?

Thanks,
Kavita

Sending them as part of the value payload isn't enough?
I used this example:

Neo4j Graph Database Platform – 29 Oct 19

Streaming Graphs: Combining Kafka and Neo4j

If you’re looking for the basics on how to turn streams into graphs with Neo4j and the Neo4j-Streams plugin, you’ve come to the right place.

can you replace the payload object rather than the published data being nested inside a payload?
