WNT_Window class equivalent for Qt 6

Hi gentlemen, I am migrating a MFC application to Qt, and I need to replace the WNT_Window by its Qt equivalent, unfortunatelly nothing is provided by OCC team.
I found some example in OCCTOverview but it is for Qt 5.x so I am not sure it will work for Qt6.

Does someone know if there is an implementation for Qt 6.x ?

Does OCC plan something to provide a "QT_Window" class ? (I remember when I started to use OCC, having WNT_Window save me a lot of time and misunderstanding).

Thanks in advance.
Best regards.
Jerome.
