HidHide not working for Steam?

Steam seems able to see the controller hidden by HidHide, even though Steam isn't in the list of apps to see through the cloak.

One of the steam games I tried can see the hidden device, too, even though it's hidden by both Steam and HidHide.

Is it intended to allow Steam to see through the cloak?

Cheers

What controller? I can't give any meaningful feedback with that little information, Steam uses a ton of APIs that all work differently depending on used controller and settings.
