Discord.py：如何从线程函数发送消息？

Question

我有以下代码：

import asyncio
import threading
import time
import discord
from discord.ext import commands
from .utils import error


class threaded:

    def __init__(self, channel, bot):
        self.channel = bot.get_channel(channel)
        self.bot = bot

    def doSomething(self):
        print("abc")


    async def IAmThreaded(self):
        time.sleep(30)
        embed = discord.Embed(title=f"Finished doing something",
                              description=f"abc",
                              color=0x000000)
        # this is where I get the error
        await self.channel.send(embed=embed)
        time.sleep(30)
        Busy.busy = False

    def threadMe(self):
        loop = asyncio.new_event_loop()
        asyncio.set_event_loop(loop)
        loop.run_until_complete(self.IAmThreaded())
        loop.close()


class Busy:
    busy = False


@commands.command()
async def something(ctx):
    if not Busy.busy:
        threadMeClass = threaded(ctx.channel.id, ctx.bot)
        embed = discord.Embed(title=f"Starting doing something",
                              description=f"abc", color=0x000000)
        await ctx.channel.send(embed=embed)
        threadMeClass.doSomething()
        Busy.bosy= True
        threading.Thread(target=threadMeClass.threadMe).start()
    else:
        await error(ctx, "There is already something running, please wait for it to finish")

当它运行时，线程会一直工作，直到它完成并尝试发送消息，当它发送时，我得到： RuntimeError: Timeout context manager should be used inside a task. 我尝试将 ctx 直接传递给类并通过保存 id 来获取频道，但它们都不起作用，有什么提示吗？
