Pyrogram does not work inside the Pytelegrambotapi Handler

Question

There is a handler for processing messages for the telegram bot. Inside under certain conditions, the Pyrogram method should operate

# coding: utf8
import telebot
from pyrogram import *
import time
bot   = telebot.TeleBot('BOTTOKEN')

@bot.message_handler(content_types=['text'])
def mes_handler(message):
    if message.text == 'Test123':
        app = Client('my_account')
        print(1)
        with app:
            print(2)
            users_data = app.iter_chat_members(groupID)
            print(users_data)

while True:
    try:
        bot.polling(none_stop=True)
    except Exception as e:
        print(e)
        time.sleep(15)

before with app: everything works, after no. (outputs only 1, 2 no, it means mistake in with app:. If i use with app: outside of handler everything works
