如何发出命令以在嵌入中发送用户个人资料图片？

How do I make a command to send the users profile picture in an embed?

我想创建一个命令 !avatar @user 来发送用户的个人资料图片，我是编码新手所以如果有人能帮助我，我会很高兴感谢。谢谢！

这是我个人使用的命令-

@client.command(aliases=['profilepic','pfp'])
async def avatar(ctx, member: discord.Member = None):
    member = ctx.author if not member else member
    embed = discord.Embed(color=0x40cc88, timestamp=ctx.message.created_at)
    embed.set_image(url=member.avatar_url)
    embed.set_footer(text=f"Requested by {ctx.author}")
    await ctx.send(embed=embed)

如有问题，欢迎评论。
