Enforce non desktop bindings:
done by mid function hooking a function in steamclient.dll the function appears to be setting the appId of the new controller bindings inject/hook right after the target launched switch focus -> binding gets changed to shortcut bindings -> hook function grabs appid hook function replaces desktop-config appid with the one grabbed everytime steam tries to active desktop-config glosc_gamelauncher unloads dll when the target closes; unloading dll patches steamclient.dll back to originalUWP_Overlay-legacy
