I am trying to implement an onboarding process for users registering to my react application. So far I managed to add a hasOnboarded prop to the app_metadata via hooks and a rule to redirect a user when hasOnboarded is false. Now I want the user to fill a form and complete the registration. But as far as I can see I have no access to user data yet. But I need the token to communicate with my backend. Is there a way to access the token?
