An example on how to use grammY's Interactive Menus plugin

	// I'm using deno
	import "https://deno.land/[email protected]/dotenv/load.ts";
	import { green } from "https://deno.land/[email protected]/fmt/colors.ts";

	import { itemsMenu } from './menus/example.menu.ts';

	const grammy = new Bot<GrammyContext>(Deno.env.get("BOT_TOKEN")\|\|""); // replace `BOT_TOKEN` inside `.env` file with your own telegram bot's token

	// attaching the menu to bot to get it to work if not we'll get the following errors inside the terminal
