How to maximize window in Squish for windows .net application

Question

I have window object but methods can not be applied because they are for Qt, so I want to ask how can I maximize .net desktop application using squish.

def main():
   startApplication("ProjectName")
   #Fail1 : Fail test case failed 'Window' Squish object has no attribute 'setWindowState'
   o = waitForObject({"text": "ProjectWindowTxt", "type": "Window"})
   o.setWindowState(Qt.WindowMaximized)
   
   #Fail 2 : 'Window' Squish object has no attribute 'acivate window'
  o = waitForObject({"text": "ProjectWindowTxt", "type": "Window"})
  o.activateWindow()
