如何让我的discord.py机器人提及我的消息中提到的某人？

import discord
from discord.ext import commands

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

@bot.event
async def on_message(message):
    # 提及的成员列表
    mentioned_members = message.mentions

    if mentioned_members:
        # 遍历每个被提及的成员
        for member in mentioned_members:
            # 使用mention方法来获取提及的格式化字符串
            mention = member.mention
            await message.channel.send(f'{mention} 你被提到了！')

    await bot.process_commands(message)

bot.run('YOUR_BOT_TOKEN')
