Wraps Stytch's register_start and register WebAuthn endpoints and the navigator.credentials web API. Call this method to prompt the user to enroll a new WebAuthn factor and save the factor in Stytch.
Call webauthn.register inside an event callback triggered by a user gesture.
You can listen for successful user updates anywhere in the codebase with the stytch.user.onChange() method or useStytchUser() hook if you are using React.
Note: If a user has enrolled another MFA method, this method will require MFA. See the Multi-factor authentication section for more details.
