Is the authoritative record of identity metadata (traits, etc) intended to be in Kratos or Hydra? If it's Kratos, how is the link made between the data in Kratos identity record and the Hydra userinfo endpoint? My understanding from here (
https://www.ory.sh/docs/oauth2-oidc/userinfo-oidc) is that the getOAuth2ConsentRequest call returns the data from the userinfo endpoint. However if all the user traits are in Kratos, how can I populate data from there? Do I just need to make another call to Kratos?
