What should I do if I get the error AttributeError: 'CallbackQuery' object has no attribute 'chat' when starting the program?

Question

Python

I run the program:

import telebot
print('******1')
from config import token
print('****2')
from telebot import types
bot = telebot.TeleBot(token)


@bot.message_handler(commands = ['start'])
def welcome(message):
  bot.send_message(message.chat.id, 'Привет, {0.first_name}!\nЧтобы поискать статьи в техноблоге по моделям нажмите /tech'.format(message.from_user, bot.get_me()), parse_mode='html')
@bot.message_handler(commands = ['tech'])
def tech(gg):
  kb = types.InlineKeyboardMarkup()
  brand1 = types.InlineKeyboardButton(text='Kingsong', callback_data = 'kingsong')
  brand2 = types.InlineKeyboardButton(text='Inmotion', callback_data = 'inmotion')
  kb.add(brand1, brand2)
  bot.send_message(gg.chat.id, "Choose a brand", reply_markup=kb)
@bot.callback_query_handler(func = tech)
def tech_ob(callback):
  if call.data == 'kingsong':
    bot.send_message('KS')
  elif call.data == 'inmotion':
    bot.send_message('Im')

bot.polling(none_stop=True)

After I click on the button, I get an error (its full code):

Python version 3.8.2, pyTelegramBotApi library is fine

Answer 1

Where is this from?
@bot.callback_query_handler(func = tech)

@bot.callback_query_handler(func=lambda call: True)
