Steam controller config?

By Doctor X, in Mansions of Madness

I've got a bad back. Being able to use the Mansions of Madness app via my Steam Machine on my TV would be a lot more convenient than hauling my laptop back and forth. It's not Steam OS supported as far as I know, so doesn't actually PLAY on the Steam Machine, it streams from the laptop. But if I can use the Steam controller to run the game on the laptop in the other room, that would be a serious bonus for me.

On the Steam Machine library page for the app, it says "Controller Configuration Required." But I get no information on "configured to what configuration." I get no cursor on the screen, and it doesn't respond to any controls I've been able to find.

Pretend I bought my Steam Machine used, so it came with no M for me to RTF. How do I make the app work, please? I'm sitting here with my newly-purchased Streets of Arkham set and want to get in a game within the next hour or so if possible.

Rephrasing.

theres very minimal control needed. I set my controller up to use the default template for wasd/mouse and it works just fine. You really only ever use the mouse pad and right click for any of the functions in app. Maybe the start button for the esc key but thats built in too.
