Adding a PaletteEditor widget in Qt Designer

[AM577]

I can create a UI in Qt Designer with GroupBoxes and Buttons.
But I can't see how to add a PaletteEditor widget into one of the GroupBoxes.
It (the PE widget) doesn't appear in the list of widgets on the left hand panel.
What am I missing, please ?

Qt Designer has a palette editor itself, but I don't think it offers it as a widget to put into your own Qt programs does it?

Don't know if it helps, but this guy https://martchus.no-ip.biz/doc/qtutilities/classQtUtilities_1_1PaletteEditor.html has a QtUtilities::PaletteEditor Class?
