Optionally, you can specify a short text description of the channel, and the type of membership: either standard, shared or private (invitation-only). Note that creating a shared channel is an _asynchronous_ operation; the call returns before the creation is finished. You can retrieve the channel with the `get_channel` method after waiting for a short while.

Note that Teams keeps track of all channels ever created, even if you delete them (you can see the deleted channels by going to the "Manage team" pane for a team, then the "Channels" tab, and expanding the "Deleted" entry); therefore, try not to create and delete channels unnecessarily.
