Can you make two apps for xbox?

Discord and Twitch themselves would need to build and publish those apps for Xbox; end users cannot add arbitrary system‑level overlays or messaging apps on Xbox.

For media or companion‑style experiences, Xbox supports Universal Windows Platform (UWP) apps packaged for Xbox. Developers can create:

1. A UWP media/companion app
   • Built either as:
     • A native XAML/C# app using MediaElement/MediaPlayer, or
     • A thin XAML host app that shows a web experience in a full‑screen WebView (WebView2 is not supported on Xbox).
   • See the high‑level architecture guidance for Xbox apps and supported technologies: Xbox Media Application Architecture and Supported technologies on Xbox.
2. Cross‑device companion experiences
   • Using Project Rome and Microsoft Graph, a developer can build cross‑device scenarios (for example, controlling or extending an experience on Xbox from a phone or PC). This is how a companion app could coordinate activity across devices, but it still must respect Xbox platform limitations and policies.

However, there are important constraints:

• UWP apps on Xbox run in a sandbox and cannot draw arbitrary overlays “on top of” other games or apps the way PC overlays (like Discord overlay) do.
• Certain UWP capabilities are limited or unsupported on Xbox, and all apps must comply with Xbox Store and certification policies.
• Any Discord or Twitch integration must be implemented by those services (or by a publisher working with them) and submitted through the Xbox app publishing process; it cannot be side‑loaded by typical console users.

So while the platform technically allows developers to build media/companion apps for Xbox, only Discord/Twitch (or partners) can provide official apps, and Xbox does not support user‑installed overlays that sit beside a running game the way described.
