What is the library/package for mass sending messages to bot users in Telegram?

Question

Node.js

There is a bot that is used by about 10,000 users and you need to send a certain message to all of them. There is a database of chat id users.
On the Internet, I saw somewhere it seems like a ready-made solution or an article on this topic, but now I can’t find it. What are ready-made solutions? It is desirable to need a package for node.js.
Thanks

for(user_id in user_ids) {
    bot.send_message("message", user_id)
}
