Var Args
Generates N command options from the specified @SlashOption or @TextOption.
The target parameter must be of type List.
You can configure how many arguments are required with numRequired.
See @MentionsString for a way to get a list of mentionable (user/member/role/channel...) without a vararg, using a single string.
Note: You are limited to one vararg parameter in text commands.
