how can I add menu button in telegram bot

You can achieve this in two ways. Either by

• using the setMyCommands method, or
• contacting @BotFather to use its /setcommands command.

I create a menu button by add a new framework " Grammy "

first install grammy : npm install grammy

seconde add this code :

const { Bot } = require("grammy");
const bot = new Bot(BOT_TOKEN); // <-- place your bot token in this string

create list of commands :

bot.api.setMyCommands([
{ command: "start", description: "إبدأ من جديد" },
{ command: "help", description: "طلب مساعدة " },
{ command: "list", description: "القائمة " },
]);
