async def check_last_media_file(message: Message):
        last_message_flag = False
        try:
            await message.bot.edit_message_text(
                text="  ",
                chat_id=message.from_user.id,
                message_id=message.message_id + 1
            )
        except TelegramBadRequest as exc:
            if (exc.message == "Bad Request: message must be non-empty" or
                    exc.message == "Bad Request: message to edit not found"):
                last_message_flag = True
        return last_message_flag
