Discord.py如何编辑表情符号设置？

import discord
from discord.ext import commands

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

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

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

@bot.event
async def on_emoji_update(before, after):
    print(f'Emoji {before.name} has been updated.')

@bot.command()
async def edit_emoji(ctx, emoji_name, new_name):
    emoji = discord.utils.get(ctx.guild.emojis, name=emoji_name)
    if emoji:
        await emoji.edit(name=new_name)
        await ctx.send(f'Emoji {emoji_name} has been updated to {new_name}.')
    else:
        await ctx.send(f'Emoji {emoji_name} not found.')

bot.run('YOUR_BOT_TOKEN')
