I'm reading about https://www.ory.sh/docs/guides/integrate-with-ory-cloud-through-webhooks#update-identity-traits and it sounds great! I'd like to "migrate" a user property from metadata_public to traits, and it seems like this gives me a way I could do it as part of the settings flow, using a hook. Since I could actually perform the mapping in the

.jsonnet

file I pass as the

body

, I'm wondering if there's any way to skip sending the data to a remote URL, and instead just treat the request body as the response? Or should I set up something like an "echo server" to do this?
