I am in the process of setting up Azure AD B2C and including an API connector in the profile creation. I use the policy Sign up and sign in from the user flows. Now I want to add a user attribute I created myself. This should not be visible under User attributes (the user should not fill this field himself) but should be filled by the API and returned under Application Claims and in the token. Is this possible with the user flows? Or is this currently only possible with the Custom policies under Identity Experience Framework?
Thanks for your answers
