How to combine schedule and bot.polling()?

Question

Python

Hello!
I have a bot that checks the performance of a certain site after a fixed period of time (for example, every half hour). For this task, I found the schedule package on the Internet, the work with the Telegram api itself is carried out through pyTelegramBotAPI. I encountered the following problem: if the scheduler works, then bot.polling does not work and vice versa, please tell me how to synchronize them.
ps this is how bot get api response but schedule is not working

def main_loop():
    bot.polling(True)
    while 1:
        schedule.run_pending()
        time.sleep(1)


if __name__ == '__main__':
    main_loop()

here is the whole script:

import telebot
from config import ACCESS_TOKEN
import config
from telebot.types import Message
import requests
import schedule
import time
import sys

bot = telebot.TeleBot(ACCESS_TOKEN)
chat_id = '434574930'


# @bot.message_handler(func=lambda message: True)
def send_message():
    req_home = requests.get(config.HOME_URL, auth=(config.LOGIN, config.PASS))
    req_ocr = requests.get(config.OCR_URL, auth=(config.LOGIN, config.PASS))
    response = ''

    #   если ответ сервера не 200
    #   пока отлаживаю, ожидаю 200 
    if req_home.status_code == 200:
        response = config.HOME_URL + " status code: " + str(req_home.status_code) + '\n'

    #   если ответ сервера не 200
    if req_ocr.status_code == 200:
        response = response + config.OCR_URL + " status code: " + str(req_ocr.status_code) + '\n'

    #   если сервер вернул ошибку
    if response != '':
        bot.send_message(chat_id, response)


#   Планировщик для бота
schedule.every(config.SCHEDULE_DELAY).seconds.do(send_message)


@bot.message_handler(commands=['start'])
def set_chat_id(message: Message):
    global chat_id
    chat_id = message.chat.id
    bot.reply_to(message, "Start checking ...")


def main_loop():
    bot.polling(True)
    while 1:
        schedule.run_pending()
        time.sleep(1)


if __name__ == '__main__':
    main_loop()

Answer 1

Threading will help I think

Answer 2

def send_message():
<...>

schedule.every(5).minutes.do(send_message)

while True:
    schedule.run_pending()
    time.sleep(1)

Answer 3

Take out the scheduler in a separate script
