如何检查我的机器人在尝试加入语音频道之前是否有查看该语音频道的权限？

import discord
from discord.ext import commands

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

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

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

@bot.command()
async def check_voice_channel(ctx, channel_id: int):
    channel = discord.utils.get(ctx.guild.voice_channels, id=channel_id)
    if not channel:
        await ctx.send("Voice channel not found.")
        return

    permissions = channel.permissions_for(ctx.guild.me)
    if permissions.view_channel and permissions.connect:
        await ctx.send(f"I have permission to view and join the voice channel: {channel.name}")
    else:
        await ctx.send(f"I do not have permission to view or join the voice channel: {channel.name}")

bot.run('YOUR_BOT_TOKEN')
