title: Print the list of members in a voice channel
body: <p>i'm coding a discord bot and I need a function that kick all members in my channel. I wrote this code:</p>
  <pre><code>@client.command()
  async def separaci(ctx):
      canale = ctx.message.author.voice.channel
      utenti = canale.members #This return an empty list
      for utente in utenti:
          await utente.edit(voice_channel = None)
  </code></pre>
  <p>I don't know why <code>canale.members</code> return an empty list. Can you help me? Thanks you :)</p>
