How do we find such info as attestationPreference through the prepareInterface() API? Is there a way to access ASAuthorizationPublicKeyCredentialRegistrationRequest? I don't seem to see how we can achieve this through ASPasskeyCredentialRequest in prepareInterface(forPasskeyRegistration:) for iOS.
A more broader question is: do we even have access to the WebAuthn extensions in third-party passkey manager?
Thanks, Joshua
