How can I implement uploading multiple files at once in aiogram?

I need to implement multiple file uploads in one message. I couldn't find how to do it in the official documentation.

For example, I implemented only loading one file at a time and storing them in a separate directory.

Now the code works in such a way that it saves files in a directory and writes the file number, so I understand how many are saved.

import os
import asyncio
import logging

from aiogram.types import Message
from aiogram import Bot, Dispatcher, types, Router, F
from aiogram.types import BotCommand, BotCommandScopeDefault
from aiogram.filters.command import Command

router: Router = Router()

logging.basicConfig(level=logging.INFO)
bot = Bot(token="")
dp = Dispatcher()

EXTENSION = '<>'
FILE = ''
counter_files = 0

UPLOAD_FOLDER = "uploads/"
os.makedirs(UPLOAD_FOLDER, exist_ok=True)

@dp.message(Command("start"))
async def cmd_start(message: types.Message):
    await message.answer("Hello!")


@dp.message(Command("check_status"))
async def cmd_start(message: types.Message):
    await message.answer("File: " + FILE)

@dp.message(Command("message"))
async def cmd_start(message: types.Message):
    await message.answer("Message: " + message.text)


@dp.message(F.document)
async def get_doc(message: types.Message, bot: Bot):
    global FILE, counter_files
    file = await bot.get_file(message.document.file_id)
    file_path = file.file_path
    
    if file_path.endswith(EXTENSION):
        destination = os.path.join(UPLOAD_FOLDER, f'file_{counter_files}.{EXTENSION}')
        await bot.download_file(file_path, destination)

        FILE = destination
        counter_files += 1
        await message.answer(f"Your {FILE} is success  downloaded!")
    else:
        await message.answer(f"Format is wrong! Download {EXTENSION}")


async def set_commands():
    commands = [BotCommand(command='start', description='start chating'),
                BotCommand(command='check_status', description='check status'),
                BotCommand(command='message', description='your message'),]
    
    await bot.set_my_commands(commands, BotCommandScopeDefault())


async def main():
    await set_commands()
    await dp.start_polling(bot)

if __name__ == "__main__":
    asyncio.run(main())
