I have an azure function that I want to send a message to a service bus that has a correlation filter on it. Specifically the correlation filter is on the label/subject with a value of 'APPLICATION'. correlation filter

How do I send the message from the azure function so that it will set this value and the subscription will receive the message?

Currently the function is set up something like this:

index.js:

module.exports = async function(context, inMessage) {
  context.bindings.outMessage = someJavascriptObject;
}

function.json:

{
  "bindings": [
    {
      "name": "inMessage",
      "type": "serviceBusTrigger",
      "direction": "in",
      "topicName": "some_topic_1",
      "subscriptionName": "SUBSCRIPTION_NAME",
      "connection": "CONNECTION_STRING_1"
    },
    {
      "name": "outMessage",
      "type": "serviceBus",
      "topicName": "some_topic_2",
      "connection": "CONNECTION_STRING_2",
      "direction": "out"
    },
  ]
}
