Loading views from various modules upon pressing Ribbon buttons in PRISM

Loading views from various modules upon pressing Ribbon buttons in PRISM

I'm developing WPF application using PRISM. I have two regions :
Ribbon region (which has got buttons to launch views from different
modules) View Region (in which views from different modules will be loaded
but one view at a time)
I have separate module assemblies for Ribbon and views (i.e.
CustomerModule, OrderModule, etc.). My ribbon has got buttons which should
load view from modules i.e. pressing "Customer" button should load the
specific view from "CustomerModule", pressing "OrderModule" should load
the specific view from "OrderModule", etc.
Can someone provide code snippet on how I should implement the command for
my ribbon buttons to launch the view from different module assemblies? I'm
not sure on how I can access the view module information into my ribbon
module?
