[keycloak-user] Client Initiated Account Linking doubt

I'm looking at this doc: https://keycloak.gitbooks.io/documentation/server_development/topics/iden... And unless your app lives inside a Java servlet guarded by Keycloak, there's no way to use this feature, right? Due to the hash generation. I don't see a way to get a client / user session Id since they're internal stuff in Keycloak associated thanks to the cookie in the user's browser. I get why it's needed though and I don't see any good alternative right now for non-servlet apps (OpenID Connect enabled apps made in other languages for instance)... but it's unfortunate that the doc doesn't clarify it. Thanks.
