Serverless App Product Event for response to Thread

I am writing an app that needs to process notes added to Freshdesk Tickets. I am able to get private and public notes but I do not see any way to get a notification when a response is made to a private note (i.e. a thread).

So for the following:


My serverless app receives notification for the original private note “new test note”.
But it does not receive a notification for responses to that thread as in:

In above, app is not invoked for “response to test note” or “Test new response”.

Here is the manifest I am using:

{
  "platform-version": "2.3",
  "product": {
    "freshdesk": {
      "events": {
        "onTicketCreate": {"handler": "onTicket"},
        "onConversationCreate": {"handler": "onConversation"}
      }
    }
  },
  "engines": {
    "node": "18.19.1",
    "fdk": "9.3.1"
  }
}

And the server.js:

exports = {
  onTicket: function(payload)  { processTicket(payload) },
  onConversation: function(payload)  { processNote(payload) }
}

function processTicket(payload) {
    log(payload)
}

function processNote(payload) {
    log(payload)
}

Is there a Product Event that I can add to capture responses to threads?
