So I have a discord bot made with python3.6, and I want him to create a text channel, but only for admins.

I know how to create a text channel using `await client.create_channel()`, but I do not know how would I set custom permissions and how would I send a message to it.

Thank you!

My code (in case you need it):

```
@client.event
async def discord.on_server_join(server):
    await client.send_message(channel, "Thank you for using Phantom. From all the developers, we want to thank you, as we know there are thousands of other bots out there.")
    await client.send_message(channel, "You should see that a new channel was created and is called \"Phantom\". That is the phantom moderation channel and is used for administrating your phantom instance.")
    server = ctx.message.server
    await client.create_channel(server, "Phantom", type=discord.ChannelType.text)

@client.event
async def on_message(message):
# The code continues here, but I think you only need the on_server_join function.

```
