Azure B2C Custom Flow Add field to login - azure

Question

I have an Azure B2C Custom Flow where I have defined the TrustFrameworkExtension.xml and signupsignin.xml. I have added the technicalProfile listed below with the expectation that a new free form text field will be added to the log in screen where the user can add their customer service rep's name. Unfortunately, this field is not added the login screen, but since I have the default value set to "Joe Representative", every login has an api call that is passing in "Joe Representative". So I have the part about passing the value to my API completed, I just need to know what I need to do to get the free form text to be displayed on the UI. Suggestions?

Answer 1

You cannot use an orchestration step with Type=CombinedSignInAndSignUp and also modify the Sign In page elements. This step type will always default to username/password regardless of adding output claims to the selfAsserted technical profile that controls the Sign In function.
