Flexible Identifiers and login_hint

[zambonichief1721]

I'm using auth-spa-js ^2.1.3, and have flexible identifiers turned on for a database connection. Right now phone and email are both optional for sign-up with OTP selected for verification on sign-up.

My application allows the user to click a sign-up button that presents a modal where the user can enter their email or phone number, before selecting continue. We're using the default Universal Login page, and when I call the loginWithRedirect and pass login_hint with their entered item, it doesn't populate on the page.

Is there a different way that it gets passed when using flexible identifiers or is this not a supported feature?
