🐛 Bug Report
Description
The rpId field appears to be missing from the SignInOptionsResponse class.
Current definition:

However, the Front Driver Interface (FDI) does include this field:

🔍 Context
The rpId field is defined in the PublicKeyCredentialRequestOptions specification and appears to be required for native passkey authentication on Android.
When the field is missing, attempting to sign in using react-native-passkey results in the following error:
{"error": "NoCredentials", "message": "No viable credential is available for the user."}
💡 Workaround
A temporary workaround is to manually inject the rpId field into the JSON response returned by the API.
✅ Expected Behavior
The rpId field should be included in the SignInOptionsResponse , as shown in the FDI documentation and required by the WebAuthn specification. This would allow native passkey authentication to work correctly without manual modification of the response.
