TypeError: 'async_generator' object is not iterable?

Question

Python

I'm writing a bot on aiogram and I need to get all the chat participants. Since aiogram cannot get the list of participants, I need to get the list of participants through pyrogram and then pass it to the bot.
my code is
bot.py

bot.ru

from aiogram import Bot, Dispatcher, executor, types
import юзербот

бот = Bot(token=config.TOKEN)
диспетчер = Dispatcher(бот)
# код...
@диспетчер.message_handler(commands=['додати'], commands_prefix='+')
async def додати(message: types.Message):
    текст = message.text
    що = текст.split(" ")[1]
    ід_чату = message.chat.id
    print(текст, що)
    if що == "юзера":
        якого = текст.split(" ")[2]      
        if якого == "цього":
            #код..
        elif якого == "всіх":
            print(await юзербот.учасники_чату(ід_чату))
#код..
if __name__ == '__main__':
    executor.start_polling(диспетчер, skip_updates=True)

userbot.ru

from pyrogram import Client, filters
from pyrogram.errors import FloodWait

app = Client("my_account")

async def учасники_чату(ід):
    await app.start()
    учасники = []
    
    for учасник in app.iter_chat_members(ід):
        учасники.append(учасник.user.id)

    await app.stop()
    return учасники

What am I doing wrong?

ps if you run userbot.ru directly (python userbot.ru) and

without async and await

from pyrogram import Client, filters
from pyrogram.errors import FloodWait

app = Client("my_account")

def учасники_чату(ід):
    app.start()
    учасники = []
    
    for учасник in app.iter_chat_members(ід):
        учасники.append(учасник.user.id)
    app.stop()
    return учасники
print(учасники_чату(-1234..))

then it works without problems. and if I get only
pps errors from the bot, maybe there is another way to do it, but I xs

The error seems to be quite understandable.
The app.iter_chat_members() method you are calling is asynchronous, and you are iterating its output with a synchronous for loop. Use
async for item in app.iter_chat_members(id):
