How can I test my game on Xbox without UWP?

A few years back I had put my game on my Xbox One S using the Xbox Dev Mode and building my game for UWP.

I was about to do the same with my current project, but when I starting hunting for the tutorials on how to do this, I found a notice form Microsoft stating:

Before investing time developing a game based on the UWP framework, please note that UWP is no longer under active development. Further, UWP based games are no longer accepted in the Xbox Store.

Well frik, I hadn’t heard about this before. So what do we even do now? Has Microsoft completely revoked their offer to let people use a retail console as a dev kit? If not, then what is the new process I need to go through to get a Unity game on my Xbox? If so, then what is the general process to be an Xbox developer going forward?

I’m surprised Unity still lets you use UWP if you cant upload projects anymore. I think UWP didn’t support a lot of features. Looks like the best option might be the GDK now (for Windows and Xbox) Unity and Microsoft announce the Microsoft GDK Packages for Unity for Unity 6 beta. I think it’s probably just as easy to sign up for an ID at Xbox and get a devkit (they’re free if the game is approved). I think this also unlocks a new section in Unity Discussions where you can talk about Xbox issues due to the NDA.

I’d probably just make the game first for PC and give it gamepad support before looking at deploying on console.
