How to track the button click event in the telegram bot?

Question

Node.js

Hello. I am writing a Node.js bot for telegram. With the help of the following code, I made such a button:

const opt = {
   parse_mode: 'markdown',
   disable_web_page_preview: false,
   reply_markup: JSON.stringify({
       keyboard: ,
       resize_keyboard: true
   })
};

app.sendMessage(id, 'text', opt)

Here are the questions:
1) how do I track the click on this button?
2) now when you click on the button, the text of the button is immediately sent to the bot. How to undo it?

Answer 1

send location
catch

bot.on('message', function (msg) {
        console.log(msg); /*тут увидите геокоординаты */
});
