Problem description
We took the decision to add x-correlator in our API which is fine but I have a doubt for notification.

Do we have to add the x-correlator as well in the POST {$request.body#/webhook/notificationUrl}? This is the notification send to the listener.

In order to stay fully compliant with CloudsEvents (I did not find any mention x-correlator in CloudsEvents) I tend to think that we must not have this x-correlator in the notification response & endpoint (for CloudsEvent compliance and to get it easy for the developer)

Expected behavior
