    except Exception as e:

        await state.finish()

как не крути код выдает ошибку после ввода номера - Ошибка при отправке кода: bytes or str expected, not
class int

Пробовал делать через with TelegramClient(StringSession(), API_ID, API_HASH) as client: но запрашивает номер и код в консоль как не крути
