QApplication instance dont have widgetAt method on Maya 2020

[miquelcampos]

in Maya 2018 works but in 2020 widgetAt method should be used from QApplication, not from an instance

from mgear.vendor.Qt import QtCore, QtWidgets, QtGui
import PySide2


qApp = QtWidgets.QApplication.instance()
qApp = qw.QApplication.instance()
dir(qApp)
dir(PySide2.QtWidgets.QApplication)

# QApplication instance don't have widgetAt method on Maya 2020

#PySide2.QtWidgets.QApplication.widgetAt(p)
