How to get all messages from the group in which he is a member in a telegram bot?

Question

Telegram

Good afternoon!
I wrote a bot that responds to the words sent to the chat, such as "Hello"
, Dorova, I'm a bot ... , by function:

if message.text == "Привет":
    bot.send_message(message.chat.id, "Дорова, я бот ...")

When using the bot in the LAN, everything works great, but if you add it to the group, then it does not respond to the words in the chat, but only responds to the words that are sent to it in response. That is, if you write to him with answers, then there is a reaction!
Question: how to make it react to words sent in a group without a dedicated response to the bot!
