How do I open a messagebox using MVVM

I have been searching for days for an easy method to open a MessageBox (ideally, any custom window) while still adhering to the MVVM architecture. From a method within the ViewModel, I need to prompt the user for some information before continuing.

All the examples I have found online appear (to me) to be extremely elaborate/intensive to get setup (such as this example Implementing Dialog Boxes in MVVM[^]) . I think part of the problem is most of the examples are using various frameworks and dependency injection that I am not using and don't fully understand, yet.

Is it possible to do this very simply - not using PRISM or MVVMLight? Or do they all require lots and lots of classes that you have to get setup before doing anything. I am really just looking for something barebones so I can get started and grow my usage and understanding from there. So far this is the only thing that has come close to appearing simple and that I kind of understand. Dialogs the MVVM Way[^]

What I have tried:

I have downloaded this example Dialogs the MVVM Way[^]. But am unsure if behaviors are the best and easiest way of doing this?

MessageBox.Show(...);

From the ViewModel? That would violate the MVVM architecture and require the ViewModel to know about the View.
