What you can try is to install the application for mobile devices, associate it to your console and then search for the game from the app.

Once you search for it, send it to install remotely to the console.

If you do not have the remote functions enabled on the console, follow these steps.

Sign in on your console using the same Xbox profile you'll be using on your mobile or PC app.

Press the Xbox button on your controller to open the guide and go to Profile & system > Settings > Devices & connections > Remote features.

Check the box to enable remote features.

For Power options, select Sleep mode.
