While under X11 we can use `winId()` to create a window indentifier.
For Wayland, a handle made with the xdg-foreign protocol is needed.
The QPA explicitly use the protocol for the File Chooser portal IIRC.
Qt consumer needs a stable API to get an handle to use portal nicely since the QPA own the exporter.
PS: It is not the same suggestion as QTBUG-73801.
