Make one of multiple NSWindow persistent across all the windows, including fullscreen windows

Question

I'm trying to create a window with border which is persistent across all the windows, including fullscreen windows. Something like what zoom does when you're sharing your scereen. Now I do have a code which works well in silo which I have pasted below i.e persists across all the screens including fullscreen apps.

But when I try to expose the same code through node bindings so that my electron application can trigger the initialization of that window, it only shows up on desktop window and the electron window (when forced with orderFront) when in fullscreen but gets hidden on other full screen apps even with orderFront or orderFrontRegardless.

When I list out all the Windows through electron context I see there are 3 windows, 1 being the electron window, 1 the newly created and one more which I'm not sure what is.

I'm new to Objective-C and native macOS development, would be grateful for any help.
