Distinguishing 404 Errors in azure-iothub Library

Hello,

I'm encountering challenges in distinguishing between different **404** errors returned by the azure-iothub library after sending a direct method. The 404 status code doesn't provide specific details, making it hard to differentiate errors like **GatewayTimeout**, **DeviceNotFound**, or **DeviceNotOnline**.

Could you please provide guidance on how to distinguish these specific error types within the 404 responses? Any assistance or insights on handling these errors effectively would be greatly appreciated.
