If you have it installed, the Xbox app will launch and allow you to connect Discord Voice chat to your Xbox console.
Discord Voice chat is coming to Xbox One and Xbox Series X/S and will allow you to chat with anyone on Discord via voice channels or group calls directly from your console.
At this point, you’ll need the Xbox app to transfer voice chat from your Discord account to your Xbox.
The update will start rolling out to Xbox Insiders today and will be available soon for all Xbox users..
