How to get messages from a VK conversation using Longpoll Python?

Question

Python

If you remove "Bot" from everywhere, then the code will work successfully in private messages, but initially it was necessary to make it work in a conversation. How to organize it? On startup, there will be similar type of errors about VkBotMessageEvent
that can't process anything.
How to fix this and add a working message handler from the conversation? (When you enter "kbd" a keyboard from json will appear, which successfully appears in a dialog with a bot, etc.)

The code

import vk_api
from vk_api import VkApi
import random, vk_api.bot_longpoll
from vk_api.bot_longpoll import VkBotLongPoll, VkBotEventType
import time

vk_session = vk_api.VkApi(token = "tokenhere" )

longpoll = VkBotLongPoll (vk_session, groupid)

vk = vk_session.get_api()

global Random

def random_id():
    Random = 0
    Random += random.randint(0, 90000000000)
    return Random

while True:
    for event in longpoll.listen():
        if event.type == VkBotEventType.MESSAGE_NEW and event.to_me and event.text:
            if event.text.lower() == "ping":
                vk.messages.send(
                    user_id = event.user_id,
                    message = "pong",
                    random_id = random_id()
                    )
            elif event.text.lower () == "kbd":
                vk.messages.send(
                    user_id = event.user_id,
                    message = "Added",
                    keyboard = open("jsonvk.json", "r", encoding="utf-8"). read(),
                    random_id = random_id()
                    )
            elif event.text.lower () == "kbdr":
                vk.messages.send(
                    user_id = event.user_id,
                    message = "Removed",
                    keyboard = open("jsovkr.json", "r", encoding="utf-8"). read(),
                    random_id = random_id()
                    )
            elif event.from_chat:
                if event.text == "1":
                    vk.messages.send(
                        chat_id = event.chat_id,
                        messages = "here",
                        random_id = random_id()
                        )

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

vk = vk_api.VkApi(token='token')
longpoll = VkLongPoll(vk)

def send(message):
  if event.from_user: # Для ЛС
    vk.method('messages.send', {'user_id': event.user_id, 'message': message, 'random_id': random.getrandbits(64)})
  elif event.from_chat: # Для бесед
    vk.method('messages.send', {'chat_id': event.chat_id, 'message': message, 'random_id': random.getrandbits(64)})

while True:
  for event in longpoll.listen():
    if event.type == VkEventType.MESSAGE_NEW and event.to_me:
      text = event.text.lower()
      u_id = event.user_id # (Если будет нужно)
      
      if text == 'ping': # Пример
        send('pong')
