// create keyboard
const kb = new Telegram.ReplyKeyboardBuilder();

bot.sendMessage({
    // ... rest parameters ...

    // build keyboard
    reply_markup: kb.build(),
});

Upload photo/video/audio/file

Using the example of sending a photo:

// 1. URL
const photo: string = 'https://telegram.org/img/t_logo.png';

// 2. File id
const photo: string = '123456789abcdefghi';

// 3. Local path
import * as fs from 'fs';
const photo: string = path.resolve('photo.jpg');

// 4. Buffer (for example, page = puppeteer.Page)
const photo: Buffer = await page.screenshot();

// 5. fs.ReadStream
import * as fs from 'fs';
import * as path from 'path';
const photo: fs.ReadStream = fs.createReadStream(path.resolve('photo.jpg'));

bot.sendPhoto({
    // ... rest parameters ...

    // passing one variable of the above
    photo,

    // you can specify the filename if you are passing Buffer
    __filename: '',
});
