keyboard: [["uno :+1:"],["uno \ud83d\udc4d", "due"],["uno", "due","tre"],["uno", "due","tre","quattro"]]

Answer 2

In your case the solution would be:

const opts = {
        reply_to_message_id: msg.message_id,
        reply_markup: JSON.stringify({
        inline_keyboard: 
        [
            [{text: 'Level 1'}],
        ]
    })
  };

You could use: https://github.com/RealPeha/telegram-keyboard

The library if focused on Telegraf, but you could use without it.

Answer 4

You just need to provide an InlineKeyboardButton object instead of plain text in your keyboard array of arrays.

bot.onText(/^\/start$/, function (msg) {
    const opts = {
        reply_to_message_id: msg.message_id,
        reply_markup: {
            resize_keyboard: true,
            one_time_keyboard: true,
            keyboard: [
              [{text: 'Level 1'}],
            ],
        }
    };

    bot.sendMessage(msg.chat.id, "I'm a test robot", opts);
});
