Grpc 服务器端流式处理 keepalive 配置

问：

我们在 c# .net 5.0 环境上实现了一个 Grpc 服务器

public void ConfigureServices(IServiceCollection services)
{
    ...
    services.AddGrpc(o =>
    {
        o.EnableDetailedErrors = true;
        // Small performance benefit to not add catch-all routes to handle UNIMPLEMENTED for unknown services
        o.IgnoreUnknownServices = true;

        o.Interceptors.Add<CustomInterceptor>();
    });
    ...
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env, IServiceProvider container, IHostApplicationLifetime lifetime)
{
    ...
    app.UseEndpoints(endpoints =>
    {
        endpoints.MapGrpcService<GreeterService>();

        endpoints.MapGet("/", async context =>
        {
            await context.Response.WriteAsync("Communication with gRPC endpoints must be made through a gRPC client. To learn how to create a client, visit: https://go.microsoft.com/fwlink/?linkid=2086909");
        });
    });
    ...
}

我们使用服务器端流连接来发送客户端通知

public override async Task Start(ConnectorRequest request, IServerStreamWriter<ClientNotification> clientStream,
    ServerCallContext serverCallContext)
{
    WaitHandle.WaitAny(new[] { context.CancellationToken.WaitHandle });
}

在移动平台上实现的客户端。 经过测试，我们发现当客户端失去连接（例如关闭wifi）时，我们没有任何异常或通知。

如何配置服务器以在客户端失去连接时断开流连接。可能类似于keep_alive设置。 我找到了 https://github.com/grpc/grpc/blob/master/doc/keepalive.md 但我不知道我应该在哪里设置它。
