Discord.py试图找出所有的"bot.wait_for“类型字符串，如"message”和"button_click“

import discord
from discord.ext import commands

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

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

@bot.event
async def on_ready():
    print(f'Logged in as {bot.user}')

@bot.command()
async def wait_for_message(ctx):
    await ctx.send("Please send a message!")
    def check(m):
        return m.author == ctx.author and m.channel == ctx.channel
    try:
        msg = await bot.wait_for('message', timeout=30.0, check=check)
    except asyncio.TimeoutError:
        await ctx.send("You took too long!")
    else:
        await ctx.send(f'You said: {msg.content}')

bot.run('YOUR_BOT_TOKEN')

try:
    msg = await bot.wait_for('message', timeout=60.0, check=check)
except asyncio.TimeoutError:
    await ctx.send("You took too long!")
else:
    await ctx.send(f'You said: {msg.content}')
