How to use the jsii._kernel.types.StatsRequest function in jsii

BeginRequest,
            _with_api_key("begin", self._serializer.unstructure_attrs_asdict),
        )
        self._serializer.register_unstructure_hook(
            EndRequest, _with_api_key("end", self._serializer.unstructure_attrs_asdict)
        )
        self._serializer.register_unstructure_hook(
            CallbacksRequest,
            _with_api_key("callbacks", self._serializer.unstructure_attrs_asdict),
        )
        self._serializer.register_unstructure_hook(
            CompleteRequest,
            _with_api_key("complete", self._serializer.unstructure_attrs_asdict),
        )
        self._serializer.register_unstructure_hook(
            StatsRequest,
            _with_api_key("stats", self._serializer.unstructure_attrs_asdict),
        )
        self._serializer.register_unstructure_hook(
            Override, self._serializer.unstructure_attrs_asdict
        )
        self._serializer.register_unstructure_hook(ObjRef, _unstructure_ref)
        self._serializer.register_structure_hook(ObjRef, _with_reference)

        self._ctx_stack = contextlib.ExitStack()

def stats(self, request: Optional[StatsRequest] = None) -> StatsResponse:
        if request is None:
            request = StatsRequest()
        return self._process.send(request, StatsResponse)

def stats(self):
        resp = self.provider.stats(StatsRequest())

        return Statistics(object_count=resp.objectCount)
