Node-telegram-bot-api: How to implement a delete message fucntion?

[usama-asfar]

This code doesn't work, I have added bot to a group and make it as an admin

bot.onText(/hi/gi, msg => {
  bot.deleteMessage(msg.message_id)
})

Error

let chat_id = msg.chat.id;
let message_id = msg.message_id;
bot.deleteMessage(chat_id, message_id);

you should do like this in groups to delete the message ....
