kafka streams headers in the produce step

[JacHub]

I think it is not possible to define headers in the producer json. Something like this:

"steps": [
    {
      "name": "produce_step",
      "url": "kafka-topic:xxxx",
      "operation": "produce",
      "request": {
        "records": [
          {
            **"headers": [
               {"type": "aaa"}
            ],**
            "key": "577152c4-26d2-4479-ae05-a7272fa81eea",
            "value": "{\"eventId\":\"577152c4-26d2-4479-ae05-a7272fa81eea\"}"
          }
        ]
      },
      "assertions": {
        "status": "Ok"
      }
