pub async fn run_grpc_server<S>(

How can we change this fn so that it support multiple grpc service? Now I can just pass one specific service, but what if I have multiple services?

pub async fn run_grpc_server<S>(
    address: SocketAddr,
    tls_settings: MaybeTlsSettings,
    service: S,
    shutdown: ShutdownSignal,
) -> crate::Result<()>
where
    S: Service<Request<Body>, Response = Response<BoxBody>, Error = Infallible>
        + NamedService
        + Clone
        + Send
        + 'static,
    S::Future: Send + 'static,
{
    let (tx, rx) = tokio::sync::oneshot::channel::<ShutdownSignalToken>();
    let listener = tls_settings.bind(&address).await?;
    let stream = listener.accept_stream();

    info!(%address, "Building gRPC server.");

    Server::builder()
        .add_service(service)
        .serve_with_incoming_shutdown(stream, shutdown.map(|token| tx.send(token).unwrap()))
        .await?;

    drop(rx.await);

    Ok(())
}

tonic itself supports we do like this:

    Server::builder()
        .add_service(service1)
        .add_service(service2)
        .add_service(...)

But I'm not an expert in rust, just I want to know how to change this function to achieve so
