enable opening closing windows via app

Any other car I had in last 20 years was able to open/close windows via remote control. Unfortunately my 2015 Model-S cannot do this. Neither via RC nor via app.

I came to know  a rumor that this function is not allowed in US. But (if that is true) what about other countries? The car knows where it is so this feature could be enabled in the App outside US (or inside a whitelisted country).

I don't see the essential difference that the roof window can be controlled via app but the side windows cannot...

 

The function is in the app, at least it is in the US. Under Controls at the top of the page there is a button that says Close (when the windows are open) and Vent when the widows are closed.
