How to connect a bot by voice channel ID?

Question

Python

Good day.
There is a code:

@bot.command()
async def join(ctx):
    channel = ctx.author.voice.channel
    await channel.connect()
@bot.command()
async def leave(ctx):
    await ctx.voice_client.disconnect()

How instead ctx.author.voice.channel, to register the ID of the voice channel

Answer 1

@bot.command()
async def join(ctx, *, voice: discord.VoiceChannel):
    # https://discordpy.readthedocs.io/en/stable/ext/commands/commands.html#converters
    # https://discordpy.readthedocs.io/en/stable/ext/commands/commands.html#keyword-only-arguments
    await voice.connect()

If you need a specific preset channel:

@bot.command()
async def join(ctx):
    await bot.get_channel(117454459249562234).connect()
