How do I access my built-in TV apps like Hulu?

I just got Cox Contour and so far we like it, but it doesn’t seem to include Hulu, which was one if the built-in apps from our LG smart TV. So now I’m trying to figure out how to access the built-in TV apps, and more specifically the Hulu app, since Contour already has Netflix and Amazon Prime.

Is there a way to access the built-in TV apps?
