Xbox launch game

You can turn on the Xbox with this custom driver:

I added the switch to Google Home, so it can be turned on via voice - I assume you can do the same with Alexa.

But it only powers it on, it can't launch a game.

There's also an Xbox SmartGlass driver that says it can send button presses, so maybe you could use that instead to launch a game? I haven't tried it myself (it is more complicated to set up).
