Laravel 5.3 Adding Cc to Notifications Email

I'm currently using Notifications for email instead of Mailables, since it allows for SMS, Slack, etc to be added later very easily, but you can't chain ...->cc(...) onto the emails. Looking at MailMessage and the inherited class SimpleMessage, as well as Notification. I'm a bit lost as to where the email is being fired off and if I can find a way to add the Cc attribute to it.
