    {
        if (StompState != StompConnectionState.Open)
            await Reconnect();

        headers.Add("destination", topic);
        if (!headers.ContainsKey("id"))
            headers.Add("id", $"sub-{_subscribers.Count}");
        var subscribeMessage = new StompMessage(StompCommand.Subscribe, headers);
        await _socket.SendInstant(_stompSerializer.Serialize(subscribeMessage));
        _subscribers.Add(topic, handler);
    }`
