// Optional arguments

About this command

After launching a FIDO2 authentication task (with the loginWithWebAuthn method), this method parses the resulting intent and if successful, the user receives a one-time authentication token.

An authentication callback task is then launched to exchange the token with the server for an access token. The access token can be retrieved with the onLoginCallbackResult method.

The WebAuthn feature must be enabled on your ReachFive account.

            failure = { error -> ... } // Return a ReachFive error
