I have a question about grpc

My question:
I know that kong can add grpc microservices,
Therefore, Kong can convert http into rpc and pass it to microservices.
However, my microservice returns rpc,
How does kong pass the rpc returned by the microservice to the http client?


HTTP Client ==(http)==> Kong ==(rpc)==> Grpc Microservices

Grpc Microservices ==(rpc)==> Kong == ??( I do not know what to do, kong support?? )??==> HTTP Client
