_Hey, I'm trying to do it differently, I start a flow with the "start flow" endpoint in zitadel using my backend app while specifying the on success redirect url and error url and get the intent id and auth url in response, later when the auth is done and the success url is called i get the intentId which i saved before and then call the get "info received by the idp" endpoint to get the user data and register the user. However i'm having issue with start flow, it doesn't return the intent id at all.
