WebAuthnCeremonyHandler

Handler for performing a WebAuthn assertion ceremony on the current platform.

Platform implementations call the native WebAuthn API (e.g., Android Credential Manager) with the server-provided challenge data and return the assertion response.

The full handshake, orchestrated by com.okta.directauth.model.DirectAuthContinuation.WebAuthn, runs as follows: the server issues a challenge, which is obtained as raw JSON via DirectAuthContinuation.WebAuthn.challengeData(); that JSON is passed to this handler's performAssertion, which invokes the platform's native WebAuthn API to run the ceremony (e.g., prompting for biometrics or a security key) and returns a WebAuthnAssertionResponse; DirectAuthContinuation.WebAuthn.proceed() then exchanges that assertion response with the server for tokens.

Most Android apps should use AndroidWebAuthnCeremonyHandler rather than implementing this interface directly.
