how to gen protobuf.Any type?

[dobet]

I have an field

message Test1 {
string name = 1;
}

message Test2 {
repeated string names = 1;
}

message Reply {
google.protobuf.Any Data = 1;
}
sometimes Reply.Data is Test2.name, sometime Reply.Data is names,
when I gen openapi , Reply.Data is ref protobuf.Any. but I want ref Test1 or Test2

What can I do?
