Trying to use WebAuthn as a signup\login

Help
1

I am trying to use WebAuthn as an only way to sign up or login.

I have made this Methods enabled (both device and biometrics) but do not see any prompt during registration.

Moreover, sign up page requires me to enter verification code from email ,while I just want to have magic link in the mailbox, not code.

Seems like additional restriction here is what is the preferred way for login
https://manage.auth0.com/#/authentication-profiles

And biometrics is not free, again. Why free options, which do not cost Auth0 anything, are made paid?
