aiogram: how to connect an inline keyboard from a function of another file with a bot file if this function will work in another code

Question

Project (connection between DRF and bot with endpoints):
-bot-directory (not in django project) : services.py and main.py in it
-folders of django apps, manage.py etc.

My function from services.py from bot directory

def get_items_kb():
    keyboard = InlineKeyboardMarkup()
    button1 = InlineKeyboardButton('Подтвердить', callback_data="yes")
    button2 = InlineKeyboardButton('Отклонить', callback_data="no")
    keyboard.row(button1, button2)
    return keyboard


async def register_manager(CHAT_ID: str):

    bot = Bot(token='same')

    fake = Faker()

    username = fake.user_name()
    password = fake.password()

    await bot.send_message(CHAT_ID, f'Подтвердите:{username}\n{password}', reply_markup=get_items_kb())

Using of this function in django-signals (signals.py)

@receiver(pre_save, sender=BotUser)
def bot_user_manager_changed(sender, instance, **kwargs):
    if instance.id is not None:
        previous = BotUser.objects.get(id=instance.id)
        if not previous.manager and instance.manager:
            register_manager_sync = async_to_sync(register_manager)
            register_manager_sync(instance.user_id)

main.py with bot in bot directory (in the same directory as the function, but different file)

storage = MemoryStorage()
TOKEN='same'
bot = Bot(TOKEN)
dp = Dispatcher(bot,
                storage=storage)

@dp.callback_query_handler(lambda query: query.data == 'yes', state="*")
@dp.callback_query_handler(lambda query: query.data == 'no', state="*")
async def activate_manager_handler(callback_query: CallbackQuery, state: FSMContext):
...



if __name__ == '__main__':
    executor.start_polling(dp,skip_updates=True)

So all I want to do is get this inline keyboard to work and be caught by the handler when the function runs from django signals. Now, the function send a message, but inline-keyboard doesn't work.

Expectation: Example of work: I change manager field to True in django-admin -> signal uses register_manager function -> manager gets a message with inline-keyboard -> he pushes the button -> my handler from main bot file catches that callback_query and do what i say.

Now, handler doesn't see inline-keyboard callbacks
