Any tutorials or sample scripts for making popup audio settings?

I have a game and on various windows(scenes) I want to be able to access the audio settings.  I figured the best way to do this is to create a seperate .lua file which I can call from each scene using the require(“audioMenu”) function.  

I am having a little bit of difficulty figuring out the best place to start, and was hoping to get access to an example script or a tutorial on how to make a “popup menu” which is accessible by many scenes. 

One of the issues, is that on my scenes, i don’t really have a lot of things going on so I don’t currently have displayGroups on them. I am not sure if I should create and put everything into display groups or if I can just create a display group in the extra lua file.  Any ideas/links would be appreciated. 

If you’re using composer for your scenes then the showOverlay function sounds like the thing you’re after.
