Detect if SKStoreReviewController has displayed app rating window on macOS

The way to ask for review

SKStoreReviewController.requestReview()

On iOS folks found pretty easy way how to find if rating window has been presented link (just by counting number of windows within the app)

How to reliably detect this on macOS? (Counting windows alternatives?)

Found that CGWindowListCopyWindowInfo + NSRunningApplication are the right things to inspect:

dispatch_time_t twoSecondsFromNow = DISPATCH_TIME_NOW + 2.0;
dispatch_after(twoSecondsFromNow, dispatch_get_main_queue(), ^{

    //HERE REQUEST REVIEW
    [SKStoreReviewController requestReview];

    dispatch_time_t secondFromNow = DISPATCH_TIME_NOW + 1.0;
    dispatch_after(secondFromNow, dispatch_get_main_queue(), ^{
        CFArrayRef windowList = CGWindowListCopyWindowInfo(kCGWindowListOptionOnScreenOnly, kCGNullWindowID);
        NSArray <NSString*>*windowNames = [(__bridge NSArray *)windowList valueForKey:@"kCGWindowOwnerName"];
        CFRelease(windowList);
        if ([windowNames containsObject:@"storeuid"]) {

            //REPORT TO PREFERENCES THAT WE SUCCESSFULLY ASKED FOR REVIEW
            NSLog(@"Rating Window was presented");
        }
    });
});

Possible alternative (as of 10.14.2 with significant delays for deactivations) :

- (void)findRunningApplication
{
    NSArray<NSRunningApplication *> *runningApplications = [[NSWorkspace sharedWorkspace] runningApplications];
    for (NSRunningApplication *app in runningApplications) {
        if ([[app bundleIdentifier] isEqualToString:@"com.apple.storeuid"]) {
            [self setRunningApplication:app];
        }
    }
}

- (void)setRunningApplication:(NSRunningApplication *)runningApplication
{
    if (runningApplication != _runningApplication) {

        if (runningApplication == nil) {
            [_runningApplication removeObserver:self forKeyPath:@"active"];
        } else {
            [runningApplication addObserver:self forKeyPath:@"active" options:NSKeyValueObservingOptionNew context:StoreInspectorKVOContext];
        }
        _runningApplication = runningApplication;
    }
}

- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary<NSKeyValueChangeKey,id> *)change context:(void *)context
{
    if (context == StoreInspectorKVOContext) {
        if (object == [self runningApplication] && [keyPath isEqualToString:@"active"]) {
            [self runningApplicationActiveHasChanged];
        }
    } else {
        [super observeValueForKeyPath:keyPath ofObject:object change:change context:context];
    }
}

One can even get what rating has user clicked with global monitor event + position from cgwindow

NSEvent *monitor = [NSEvent addGlobalMonitorForEventsMatchingMask:(NSEventMaskLeftMouseDown)
                                                          handler:^(NSEvent *event) {
                                                              NSLog(@"%@",event);
                                                          }];
