When using slash command options, if the slash command is asking for a channel type, make sure that the types show up as both ints and names, so that you don't have to go into documentation while trying to do a slash command. (if this behavior still exists)

[jdelucca]

Looking into it, when using the channel type as an option, first Option recognizes that the option of class Enum, then overrides the description with the inspect.getdoc() of the enum. Because there was no docstring for the enum classes, you would get "No description provided" even when you gave the Option a description string.
