Custom Webhook Response?

Are we able to manipulate the response data sent to Webhooks from themselves?

Like when you get a GET/POST request, we can send something custom back with the data sent in the query/header/body from the request.

For mode “On Received” it is currently only possible to define a response code. For mode “Last Node” it is however already possible to return custom data. That can be either JSON or binary data.

An example with binary data can be found here, but works the same with JSON data:
