Question about how apps run on Google PC Games

Recently got an email from Google Play saying my game will be put in the Google Play Games PC store. Sent a message to Google themselves about it, but they’re not very helpful when it comes to this platform.

Does anyone else here have an app that’s been submitted through the Play Console that’s also being listed on Google’s PC store? I mainly want to know how it runs from a user end perspective, because my app has been optimised to have different functions, inputs, etc, when run on a PC, but as far as I’m aware with Google Play, all I’ve ever submitted for their store is the .aab version, which runs with all the touch screen functionalities.
