    Console.WriteLine("Connection opened");
    sockJs.Send("foo");
});
sockJs.AddEventListener("message", (sender, e) =>
{
    var stringifiedArgs = string.Join(",", e.Select(o => o?.ToString() ?? null));
    Console.WriteLine($"Message received: {stringifiedArgs}");
    if (e[0] is TransportMessageEvent msg)
