	Name:            "Undelete",
	Aliases:         []string{"ud"},
	Description:     "Views the first 10 recent deleted messages. By default, only the current user's deleted messages will show.",
	LongDescription: "You can use the `-a` flag to view all users delete messages, or `-u` to view a specified user's deleted messages.\nBoth `-a` and `-u` require Manage Messages permission.\nNote: `-u` overrides `-a` meaning even though `-a` might've been specified along with `-u` only messages from the user provided using `-u` will be shown.",
