unused message don't gen swagger ?

[dobet]

I have 2 message used to an Any field

message AnyItem {
  option (openapi.v3.schema) = {
    title: "AnyItem";
    required: "true";
  };
  map<string, string> data = 1;
}

message AnyItem2 {
  option (openapi.v3.schema) = {
    title: "AnyItem2";
    required: "true"
  };
  repeated string data = 1;
}

// The response message containing the greetings
message HelloReply {
  string name = 1;
  repeated google.protobuf.Any data = 2 [
    (openapi.v3.property) = {
      required: [
        "AnyItem", "AnyItem2"
      ]
      items: {
        schema_or_reference: [
          {
            reference: {
              _ref: "#/components/schemas/AnyItem"
            }
          },
          {
            reference: {
              _ref: "#/components/schemas/AnyItem2"
            }
          }
        ]
      }
    }
  ];
}

but I got an openapi.yaml that don't have AnyItem and AnyItem2, and protobuf.Any don't convert

        helloworld.v1.HelloReply:
            type: object
            properties:
                name:
                    type: string
                data:
                    required:
                        - AnyItem
                        - AnyItem2
                    type: array
                    items:
                        - $ref: '#/components/schemas/google.protobuf.Any'
                        - $ref: '#/components/schemas/AnyItem'
                        - $ref: '#/components/schemas/AnyItem2

what can I do , the helloReply can ref AnyItem and AnyItem2?

I have the same issue, somtimes I hope to define some global components based on the message, which can be referenced when needed. but It seems that only messages referenced by the defined RPC service are effective
