How to show overlay on top of all other APP

I'm trying to display overlay on screen by following code:

 NSRect windowRect = [[NSScreen mainScreen] frame];
    self.overlayWindow = [[NSWindow alloc] initWithContentRect:windowRect
                                                          styleMask:NSWindowStyleMaskBorderless
                                                backing:NSBackingStoreBuffered
                                                  defer:NO
                                                 screen:[NSScreen mainScreen]];

    [self.overlayWindow setReleasedWhenClosed:YES];
  
    [self.overlayWindow setBackgroundColor:[NSColor colorWithCalibratedRed:0.0
                                                              green:1.0
                                                                      blue:0.0
                                                              alpha:0.1]];
    [self.overlayWindow setAlphaValue:1.0];
    [self.overlayWindow setOpaque:NO];
    [self.overlayWindow setIgnoresMouseEvents:NO];
    [self.overlayWindow makeKeyAndOrderFront:nil];
    self.overlayWindow.ignoresMouseEvents = YES;
    
    self.overlayWindow.level = NSScreenSaverWindowLevel;
    self.overlayWindow.collectionBehavior = NSWindowCollectionBehaviorCanJoinAllSpaces | NSWindowCollectionBehaviorCanJoinAllApplications;

But when other APP enter full screen, the overlay disappears even I set the collectionBehavior with option NSWindowCollectionBehaviorCanJoinAllApplications. Is it possible to display a overlay on top of all other APPs?
