When creating an open channel or a group channel, you can additionally specify a custom channel type to subclassify channels. This custom type takes on the form of a string, and can be useful in searching or filtering channels.
customType properties of a channel object allow you to append information to channels. While both properties can be used flexibly, common examples for
customType include categorizing channels as "Personal" or "Work."
To get a channel's custom type, read
channel.customType for both open and group channels.
