UWP Add-ons and Downloadable conteng

I've not found anything covering this. My game is an episodic game but I'm not sure how to build and upload the new Episodes so they can be added to the main game. I'm using Unity 2017.2f3 with an Xbox Creator account. The closest I've found to this pertained to Asset Bundles made in the Asset Bundle Browser. I tried asking on the Microsoft Forums but no answer. The documentation doesn't seem to mention UWP. How do I build and upload DLC in Unity to the Window Store?

 

I've so far gotten as far as building the package in the Asset Bundle Browser and programming the app to accept it, which works on the local machine, when it's present but I'm really confused about how to upload it to the store. The documentation really isn't very clear about publishing Asset bundles after they're built. I've only used Visual Studio 2017 to build my apps. Will this work with VS? I've seen that for the windows store using WWW.assetbundle action works best for UWP but am I targeting my store URL or the URL of the Asset Bundle?

 

So far I only get as far as using it in the Editor but how do you get this to work in a build? I haven't found much in the way anything useful for builds except maybe using Www.assetbundle which involves hosting the package on an external server. How would I test it on a build natively?
