Question

Python

How to make it so that when you press the "back" button, it returns one level back, or when you press the "home" button, it returns to the initial menu. The menu code is below:

import telebot
from telebot import types

bot = telebot.TeleBot(config.token)

@bot.message_handler(commands=["start"])
def start(m):
    msg = bot.send_message(m.chat.id, "Вас приветствует Бот")
    keyboard = types.ReplyKeyboardMarkup(resize_keyboard=True)
    keyboard.add(*[types.KeyboardButton(name) for name in ['О компании', 'Прайс-лист']])
    keyboard.add(*[types.KeyboardButton(name) for name in ['Акции', 'Контакты']])
    bot.send_message(m.chat.id, 'Выберите в меню что вам интересно!',
        reply_markup=keyboard)
    bot.register_next_step_handler(msg, name)

def name(m):
    if m.text == 'О компании':
        keyboard = types.ReplyKeyboardMarkup(resize_keyboard=True)
        keyboard.add(*[types.KeyboardButton(advert) for advert in ['Сертификаты']])
        keyboard.add(*[types.KeyboardButton(advert) for advert in ['В начало']])
        bot.send_message(m.chat.id, 'инфа о компании',
            reply_markup=keyboard)
    elif m.text == 'Прайс-лист':
        keyboard = types.ReplyKeyboardMarkup(resize_keyboard=True)
        keyboard.add(*[types.KeyboardButton(advert) for advert in ['Общий', 'Одиночный']])
        keyboard.add(*[types.KeyboardButton(advert) for advert in ['В начало']])
        bot.send_message(m.chat.id, 'Выберите прайс который нужен.',
            reply_markup=keyboard)
    elif m.text == 'Акции':
        keyboard = types.ReplyKeyboardMarkup(resize_keyboard=True)
        keyboard.add(*[types.KeyboardButton(advert) for advert in ['В начало']])
        bot.send_message(m.chat.id, 'Сожалею, но в данный момент акций нет(',
            reply_markup=keyboard)

Inline keyboard
@bot.callback_query_handler(func=lambda call: True)
def callback_inline(call):
    if call.data == "comproxy":
        comproxy_keyboard = types.InlineKeyboardMarkup()
        call_button_comproxy_restart = types.InlineKeyboardButton(text="Restart", callback_data="comproxy_restart")
        call_button_comproxy_status = types.InlineKeyboardButton(text="Status", callback_data="comproxy_status")
        call_button_comproxy_back = types.InlineKeyboardButton(text="Назад", callback_data="back")
        comproxy_keyboard.add(call_button_comproxy_restart, call_button_comproxy_status)
        comproxy_keyboard.add(call_button_comproxy_back)
        bot.edit_message_text(chat_id=call.message.chat.id, message_id=call.message.message_id, text="Выберите:",
                              reply_markup=comproxy_keyboard)

    elif call.data == "back":
        back_keyboard = types.InlineKeyboardMarkup()
        call_button_back_comproxy = types.InlineKeyboardButton(text="Comproxy", callback_data="comproxy")
        call_button_back_ser2net = types.InlineKeyboardButton(text="Ser2net", callback_data="ser2net")
        call_button_back_cups = types.InlineKeyboardButton(text="Cups", callback_data="cups")
        back_keyboard.add(call_button_back_comproxy, call_button_back_ser2net)
        back_keyboard.add(call_button_back_cups)
        bot.edit_message_text(chat_id=call.message.chat.id, message_id=call.message.message_id,
                              text='Чего изволите, господин?', reply_markup=back_keyboard)

I did through state. There is an array of users, and each user stores the current state in his object, and when you click back, the current state is checked, and returns to the corresponding menu
