How do I use InlineKeyboard with a telegram bot that uses Flask?

I am using pyTelegramBotApi and Flask on PythonAnywhere. The bot works fine, however i need to use an InlineKeyboard with it. How do I do this? Everywhere I look, people use a function, but that doesn't work with Flask. My current code is:

from flask import Flask, request
import telebot
from telebot import types
import urllib3
import datetime


secret = "secret"
bot = telebot.TeleBot(TELEGRAM_TOKEN)

app = Flask(__name__)

@app.route('/{}'.format(secret), methods=["POST"])
def telegram_webhook():
    update = request.get_json()
    if "message" in update:
        text = update["message"]["text"]
        chat_id = update["message"]["chat"]["id"]
        if text == "/start":
            bot.send_message(chat_id, ".....", reply_markup=types.ReplyKeyboardMarkup())
            markup = types.ReplyKeyboardMarkup(resize_keyboard=True)
            item1 = types.KeyboardButton("option1")
            item2 = types.KeyboardButton("option2")
            markup.add(item1, item2)
            bot.send_message(chat_id, ".....", reply_markup=markup)
        elif text == "Каждый день":
            bot.send_message(chat_id, ".....")
            markup = types.InlineKeyboardMarkup()
            markup.row_width = 2
            markup.add(types.InlineKeyboardButton("Yes", callback_data="cb_yes"),
                               types.InlineKeyboardButton("No", callback_data="cb_no"))
            bot.send_message(chat_id, "test", reply_markup=markup)
    return "ok"

I want to know how to get callback data from the button the user presses. How do I do that with this code?

We can help you with PythonAnywhere features, but for more general questions like that you need to ask in more general forums.
