Window on top off fullscreen, can we do it like steam or overwolf

So I know it's "not possible" to put a window on top of a real fullscreen app or game.
But how does Overwolf or Steam do it? Programming DirectX or OpenGL? Taking control as launcher? (afterwards for Overwolf must be then)
Anyway, my real question is: Is there any way we can do it nonetheless in Autohotkey by mimicking their methods?

All is possible. ;)
If this will not help (all code for ahk v1)

then need to inject into process and hook directx, like it does steam.

Also You can read algorithm here and if needed convert to ahk
