fromSignal() is absent in PySide6.QtCore.QMetaMethod

I'm not sure is it a problem of PySide or global Qt problem as I can't check the same code with C++.

I tried to execute this piece of code:

from PySide6.QtCore import QMetaMethod
signal = QMetaMethod.fromSignal(view_header.sectionDoubleClicked)

And got an error:

AttributeError: type object 'PySide6.QtCore.QMetaMethod' has no attribute 'fromSignal'

The code itself is taken from Qt Documentation so I assume it to be valid.

 QMetaMethod fromSignal(PointerToMemberFunction signal)
