尝试使用while循环重复扫描Discord机器人中的用户响应，但不起作用

import discord
from discord.ext import commands

intents = discord.Intents.default()
intents.messages = True

bot = commands.Bot(command_prefix='!', intents=intents)

async def check_user_response():
    # 这里可以放置检查用户响应的逻辑
    print("Checking for user response...")

@bot.event
async def on_ready():
    print(f'Bot is ready. Connected to {len(bot.guilds)} guilds.')
    while True:
        await check_user_response()
        await asyncio.sleep(1)  # 每秒检查一次，避免过度占用资源

@bot.event
async def on_message(message):
    if message.author == bot.user:
        return
    if message.content.startswith('!hello'):
        await message.channel.send('Hello!')

bot.run('YOUR_BOT_TOKEN')
