如何仅对特定消息使用wait_for("reaction_add")函数？discord.py

import discord

client = discord.Client()

@client.event
async def on_ready():
    print('Bot is ready')

@client.event
async def on_message(message):
    if message.content == '!react':
        # 发送一条消息，并获取该消息对象
        sent_message = await message.channel.send('React to this message')

        # 添加特定的反应
        await sent_message.add_reaction('👍')

        # 定义一个检查函数，用于判断是否为特定消息的反应事件
        def check(reaction, user):
            return user == message.author and str(reaction.emoji) == '👍' and reaction.message.id == sent_message.id

        # 等待特定消息的反应事件发生
        reaction, user = await client.wait_for('reaction_add', check=check)

        # 打印出触发事件的用户和反应的emoji
        print(f'{user} reacted with {reaction.emoji}')

client.run('YOUR_BOT_TOKEN')
