macos - mac python , how to bring a child window to front

I'm trying to activate a child window by python. First of all , run an app , click a button, then popup a new child window. Using python to find the window by title, and activate it.

from AppKit import NSWorkspace
from Quartz import (CGWindowListCopyWindowInfo, kCGWindowListOptionOnScreenOnly, kCGNullWindowID)
from Cocoa import NSApplicationActivateIgnoringOtherApps


print('--- running applications ---')
runningApps = NSWorkspace.sharedWorkspace().runningApplications()
for app in runningApps:
    print(app)

wndList = CGWindowListCopyWindowInfo(kCGWindowListOptionOnScreenOnly, kCGNullWindowID)
# print('----------> wndList')
for wnd in wndList:
    # print(wnd)
    if wnd["kCGWindowName"] == "some title":
        print('--- found ---')
        print(wnd)
        # ---------here, how to activate the window?
        # follow code doesn't work, it's just active the main window, not the child window
        # app.unhide()
        # app.activateWithOptions_(NSApplicationActivateIgnoringOtherApps)
        break

The main process id is 6960 and the child window's "kCGWindowOwnerPID" is 6960. It means ,the process 6960 has two windows. How to bring the child window to front?
