///     // Create an instance of EppClient, specifying the name of the registry as in
///     // the config file

///     // send it to the registry and receive a response of type EppContactCheckResponse
///     let response = client.transact::<_, EppContactCheckResponse>(&contact_check).await.unwrap();
