如何在python中创建on reaction，add role命令？

import discord
from discord.ext import commands

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

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

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

@bot.event
async def on_reaction_add(reaction, user):
    # 检查是否为特定消息的反应
    if reaction.message.id == 1234567890:  # 替换为你想要监听的消息ID
        # 检查是否为特定反应表情
        if str(reaction.emoji) == '✅':  # 替换为你想要监听的表情
            # 获取角色对象
            role = discord.utils.get(user.guild.roles, name='Role Name')  # 替换为你想要添加的角色名字
            if role:
                await user.add_roles(role)
                print(f'{user.name}被添加了角色{role.name}')

bot.run('YOUR_BOT_TOKEN')  # 替换为你的机器人令牌
