How to catch? who invited how many to the telegram chat (group)?

Question

Python

Tell me how to catch the event, who and how many users invited to the telegram chat.

@dp.message_handler(content_types=['ChatJoinRequest'])
async def on_user_joined(message: types.Message):
    await bot.chat_join_request(
                      message.chat.id,                                   
                      message.from_user.id)
    await update.message()

and did so: But how, I didn’t find any examples on the net, but I stuck this code from another code, there was an invitation by reference.

@dp.chat_join_request_handler()
async def on_user_joined(message: types.Message):
    await bot.chat_join_request(
                      message.chat.id,                                   
                      message.from_user.id)
    await update.message()

In the console I saw this

INFO:aiogram.contrib.middlewares.logging:Received chat member update for user [ID:1621id]. Old state: {'user': {'id': 1956id, 'is_bot': False, 'first_name': 'Дмитрий', 'username': 'nik', 'language_code': 'ru'}, 'status': 'left'} New state: {'user': {'id': 195id, 'is_bot': False, 'first_name': 'Дмитрий', 'username': 'nik', 'language_code': 'ru'}, 'status': 'member'} 
INFO:aiogram.contrib.middlewares.logging:Process update [ID:2619id]: [success] (in 1 ms)
INFO:aiogram.contrib.middlewares.logging:Received message [ID:20id] in chat [supergroup:-100177id]

How to output a string to the group, on behalf of the Bot that Dmitry invited 10 users, or write it to a json file and by day.
