func main() {
	ctx, cancel := signal.NotifyContext(context.Background(), os.Interrupt)
	defer cancel()

	telegramBotToken := os.Getenv("EXAMPLE_TELEGRAM_BOT_TOKEN")

	opts := []bot.Option{
		bot.WithDefaultHandler(defaultHandler),
	}

	b := bot.New(telegramBotToken, opts...)

	b.Start(ctx)
}

var (

		{ID: "4", Text: "node 4", Keyboard: [][]dialog.Button{{{Text: "Back to 3", NodeID: "3"}}}},
	}
)

func defaultHandler(ctx context.Context, b *bot.Bot, update *models.Update) {
	d := dialog.New(dialogNodes)

	d.Show(ctx, b, strconv.Itoa(update.Message.Chat.ID), "start")
}
