The ResponseId property returns the identifier associated with
the most recent response received from the provider. This value is
assigned by the provider and is typically included in the response
metadata returned by the service.
The format and meaning of the response identifier are provider-specific
and may vary between providers or models. Applications should treat
this value as an opaque string and should not depend on a specific
format or naming convention. If the provider does not include a response
identifier in the response metadata, this property returns an empty string.
