How do I build bot for business accounts?

[postvein]

I have a telegram premium account and I can connect my bot to chatbots in business account settings.
I've tried to get info about the new incoming connections and messages but I am not getting any result with this code:

from telebot import TeleBot
from telebot.types import Message, BusinessConnection

TOKEN = "<bot token>"

bot = TeleBot(TOKEN)

@bot.message_handler(commands=["start"])
def start(message: Message):
    bot.send_message(message.from_user.id, f"hello, {message.from_user.first_name}")

@bot.message_handler(regexp="ping")
def ping(message: Message):
    bot.send_message(message.from_user.id, "pong")

@bot.business_connection_handler()
def connect(connection: BusinessConnection):
    print("got business connection")

@bot.deleted_business_messages_handler()
def delete(connection: BusinessConnection):
    print("got business connection deleted")

@bot.edited_business_message_handler()
def edit(message: Message):
    print("got business connection edit")

@bot.business_message_handler()
def handle(message: Message):
    print("got business message")


if __name__ == "__main__":
    bot.infinity_polling()

How do I start doing something like in the example video of 7.2 API release?

Hello,
You have to specify business updates to allowed_updates list in infinity_polling().
