How to create a ros service in unity of type std_srvs/Empty

Hi,

I followed the tutorials provided on github for creating service in ros using custom message. I want to use std_srvs/ Empty type for the service. Does unity support default types of services or I am required to generate message for default types also?

add the line at top

using RosMessageTypes.Std;

and then use EmptyRequest and EmptyResponse accordingly.
