How to make a telegram bot automatically send messages at a given time in Python, Telebot?

Question

Python

I am making a telegram bot to send weather information at a given time.
The automatic weather reporting function does not work.
It is necessary that the bot automatically sends a message, and does not respond to the sent one.

import telebot
import pyowm
from pyowm.exceptions.api_response_error import NotFoundError
import time
from datetime import datetime

bot = telebot.TeleBot("TOKEN")
owm = pyowm.OWM('ID', language='ru')

@bot.message_handler(commands=['start', 'help'])
def send_welcome(message):
    bot.send_message(message.chat.id,
                     "*Привет! Я бот прогноза погоды, я могу сообщать данные о погоде в выбранное время.*"
                     + '\n\n' + "_Укажите город:_", parse_mode="Markdown")


@bot.message_handler(content_types=['text'])
def get_city(message):  # выбор города
    try:
        owm.weather_at_place(message.text)
        city = "Успешно! Город " + "*" + message.text + "*" + " выбран" + "\n\n" \
               + "Теперь введите _время_ *(0-23 часов)*, в которое хотите получать уведомления о погоде:"
        bot.send_message(message.chat.id, city, parse_mode="Markdown")
        bot.register_next_step_handler(message, get_indicated_time)

        return get_city

    except pyowm.exceptions.api_response_error.NotFoundError:
        bot.send_message(message.chat.id,
                         "*Город введен не корректно / не найден.* \n\n _Пожалуйста, повторите попытку_",
                         parse_mode="Markdown")


def get_indicated_time(message):  # выбор времени
    try:
        indicated_time = message.text
        if 0 <= int(indicated_time) < 24:
            correct_number = "_Время_ выбранно успешно!" + "\n\n" "Уведомление о погоде придет в *" \
                             + indicated_time + "* час(a/ов)"
            chat_id = message.chat.id
            bot.send_message(message.chat.id, correct_number, parse_mode="Markdown", reply_markup=keyboard1)
            bot.register_next_step_handler(message, send_notice)

        elif int(indicated_time) < 0 or int(indicated_time) > 23:
            wrong_number = "*Неверное время*"
            bot.send_message(message.chat.id, wrong_number, parse_mode="Markdown")
            bot.register_next_step_handler(message, get_indicated_time)
    except ValueError:
        wrong_answer = "Введите время *(0-23 часов)*:"
        bot.send_message(message.chat.id, wrong_answer, parse_mode="Markdown")
        bot.register_next_step_handler(message, get_indicated_time)


def send_notice(chat_id): # отправка сообщения о погоде
    indicated_time = get_indicated_time
    city = get_city
    chat_id = get_indicated_time
    while indicated_time == datetime.now().hour:
        observation = owm.weather_at_place(city)
        w = observation.get_weather()
        temp = w.get_temperature('celsius')['temp']
        notice_city = "*" + city + ":" "*" + "\n" + "Темп. " + "_" + str(temp) \
                      + "°C_" + ", " + w.get_detailed_status()
        bot.send_message(chat_id, notice_city, parse_mode="Markdown")
        break

bot.polling(none_stop=True, interval=0)

you can try to put the send script in cron
