User Name Hints

Feature: Login Hint: upon taking customer to signup for username and password creation, the customer needs to be able to receive a suggested username.
When there are multiple identifiers, we need to be able to use login hint to suggest a username, and in particular using and populating email address as the username identifier.

Description: We are unable to use login hint to suggest a username, after we get registration token, and check Pre-Registration,
We are unable in app metadata to pass a suggested username, particularly email address as the suggested username.

Use-case:
Upon navigating to signup completion for username and password creation, we want to be able to pass and fill a suggested username into the username field, namely the customer’s email address.

Use-case: Tell us what you are building. How would the feedback/feature improve your experience?
