Python Telegram Bot why doesn't scheduled messages work in a separate thread?

Question

Python

import telebot
import time
import schedule
import threading

def thread(my_func):
    def wrapper(*args, **kwargs):
        my_thread = threading.Thread(target=my_func, args=args, kwargs=kwargs)
        my_thread.start()
    return wrapper

@thread
def job_utro():
  bot.send_message(6341*1231,"Доброе утро!")
def job_vecher():
  bot.send_message(6341*1231,"Спокойной ночи!")
def job_usluga():
  bot.send_message(6341*1231,"У меня для тебя кое-что есть...")

schedule.every().day.at("8:00").do(job_utro)
schedule.every().day.at("22:00").do(job_vecher)
schedule.every().sunday.at("18:39").do(job_usluga)
while True:
  schedule.run_pending()
  time.sleep(1)
