Deploy game for XBOX

Hello, community. We are going to deploy our games to Consoles, And I still wait for answer from Microsoft, But maybe you can help :).

I found Microsoft creator program Xbox, where is mentioned that you can became certified developer and can develop for Unity, MonoGame etc. But I can not find UE4 in this list.

There is other Microsoft program ID@XBOX, which is OK, but It required more details from the company. And now we just want to make some experiments, but they require game concept, etc.

I Know that is COULD possible to deploy apps to RETAIL XBOX, without DEV KIT.

SO, my question, What Is the proper way to Develop/Deploy to XBOX??
I’ll be happy any input from you guys :slight_smile: Have a nice day!
