How to send messages to users of the VK bot?

Question

Python

Hello, maybe you will say that there are a lot of such topics on the Internet, but it does not help me, still I would like to get help from you.
I have a regular VK bot that responds to messages (Hello -> hi). How can I implement sending a message to all users of the bot at a certain time, I tried many options for shedul, realtime, nothing happened.
I want to make the bot, for example, at 12:00 write to all users "Good day", and then in the evening at 18:00 "Good evening"
Code:

import random
import vk_api
from vk_api.longpoll import VkLongPoll, VkEventType

def write_msg(user_id, message):
    vk.method('messages.send', {'user_id': user_id, 'message': message, 'random_id': random.randint(0, 2048)})


# API-ключ созданный ранее
token = "key"

# Авторизуемся как сообщество
vk = vk_api.VkApi(token=token)

# Работа с сообщениями
longpoll = VkLongPoll(vk)


print("Бот запущен")

# Основной цикл
for event in longpoll.listen():

    # Если пришло новое сообщение
    if event.type == VkEventType.MESSAGE_NEW:

        # Если оно имеет метку для меня( то есть бота)
        if event.to_me:

            # Сообщение от пользователя
            request = event.text

            # Каменная логика ответа
            if request == "привет".title():
                write_msg(event.user_id, "Хай")
            elif request == "пока":
                write_msg(event.user_id, "Пока((")
            else:
                write_msg(event.user_id, "что?")

Thanks for your help, I hope you understand

You create a thread, it has an infinite loop that checks the time and sends out if necessary
