Hi, I am setting up bidirectional contract testing with an external provider, and they ask me if there are any possibilities for them to receive a notification with the comparison results after they've uploaded their new OAS file. Naturally I thought it would be possible with a webhook. But I've just tried a simple example where I have set up a webhook, and upload a modified OAS file with breaking changes, and the webhook does not seem to trigger. Am I missing anything here?
