QAction.setMenu is deprecated, what is the recommended alternative?

I'm migrating a Python desktop application from Qt5 to Qt6 (i.e. from PySide2 to PySide6). The old code has some calls to QAction.setMenu(...), which is not supported in the newer version, as I get AttributeError: 'PySide6.QtGui.QAction' object has no attribute 'setMenu' when running the program.

Although issue PYSIDE-1627 is about this, my understanding is that it is Python-specific. However, the general documentation also points out that this function is deprecated. While other functions discussed on that page come with remarks such as "use X in module Y instead", setMenu does not.

I'd like to understand whether there is a plan for resolving it in the future versions of PySide, or if one is supposed to take another approach altogether.

What's your use-case?
You could replace your QAction with a "real" QMenu or a QPushButton... Most people often mistaken that QAction has no graphical interface (as you can imagine from the name "action").
Only if you place a QAction in a menuBar or something like that, it creates a graphical representation of it.... using a QWidget.... and most of the time... a QPushButton.
I think they removed it, because it doesn't make too much sense and just causes confusion about what QAction really is.

Edit:
My theory could be wrong... but to confirm:

https://doc.qt.io/qt-6/qpushbutton.html#setMenu

For example, QPushButton::setMenu is still legit :))

Thanks for your feedback! If I replace the QAction with a QPushButton, I run into a problem later, where several actions are used in .addActions(...) of a widget derived from QFrame.

It is a rather big legacy application, and I have no full awareness of what it is doing, because I'm not porting my own code and I don't know what the end result ought to look like. Thus, I don't have the foresight to understand what other parts are affected if I change a thing.

So I was hoping someone could shed some light on QAction.setMenu, which would allow me to make progress by dealing with one piece of the puzzle at a time.
