When calling the oauth2/v1/token endpoint after verification has been completed I cannot seem to get any custom claims to return in either the ID or Access token. Not sure if this is by design or if there is some configuration that I am missing.
The Org Authorization Server (which uses endpoints like /oauth2/v1/token and /oauth2/v1/device/authorize) do not support custom claims. If you want to use your custom auth server instead, insure that you are using it as the base Url for your requests.
