Attach a new provider access to the user's account. If the provider uses an authentication flow where customer credentials have to be presented, use the information from the catalog to identify available input fields. All mandatory (is_optional=false) public (is_secret=false) fields have to be provided when creating an access. All credentials that are sent with the request are securely stored in the finX backend.
