Discord.py (重写)如何检查机器人是否已经在您要求它加入的通道中？

import discord

async def check_bot_in_channel(guild_id, channel_id):
    guild = discord.utils.get(bot.guilds, id=guild_id)  # 获取服务器对象
    channel = discord.utils.get(guild.channels, id=channel_id)  # 获取通道对象

    voice_states = guild.voice_states  # 获取服务器中所有成员的语音状态

    for member in voice_states:
        if voice_states[member].channel == channel:  # 判断成员所在的语音通道是否与指定通道相同
            return True

    return False

is_in_channel = await check_bot_in_channel("服务器ID", "通道ID")
if is_in_channel:
    print("机器人已经在指定通道中")
else:
    print("机器人不在指定通道中")
