如何在discord.py中编辑临时消息

import discord
from discord.ext import commands

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

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

@bot.command()
async def edit_message(ctx, message_id: int, *, new_content: str):
    try:
        message = await ctx.channel.fetch_message(message_id)
        await message.edit(content=new_content)
        await ctx.send(f"Message with ID {message_id} has been updated.")
    except discord.NotFound:
        await ctx.send("Message not found.")
    except discord.Forbidden:
        await ctx.send("I don't have permission to edit that message.")
    except discord.HTTPException as e:
        await ctx.send(f"An error occurred: {e}")

bot.run('YOUR_BOT_TOKEN')
