How can I use Continuum with my Lumia 950 and my Xbox One?

[Windows Central Question]

I'm trying to use Continuum with my Lumia 950, using my Xbox One as the display device. I've heard that the Xbox One supports Miracast as a receiving device, but I can't figure out how to make it happen anywhere.

The "Wireless Display" app that people talk about using is nowhere to be found in the store. I have a feeling that if I could get that far at least I could figure out the rest.

Any help would be hugely appreciated. Thank you!

The wireless display app is only available for those in the preview program, so if you aren't a member of that you won't be able to use Continuum with the Xbox
