QA: `google.protobuf.Any` mapping when expected type is specified

[WizMe-M]

I have an operation that works like google.longrunning.Operation (src here)

As it seen here and here, there is an option to specify Any's type.

So, when I create rpc and specify option of what metadata and response type are:

rpc StartOperation(StartOperationRequest) returns (operation.v1.Operation) {
  option (operation.v1.operation) = {
    metadata: 'MyMetadata'
    response: 'MyResult'
  };
}

I want to grpc-api-gateway to convert these Anys into specified messages.

Is it possible to?

Also I do expect that Any will have only necessary fields (no type and value) when:

• OpenAPI specification is generated
• Response with Any is sent to a client
