Set browserWindow Always on top, even other app is in fullscreen [Electron, MAC OS]

Question

it's possible to use custom window level in Electron Framework, for make window always on top, even other apps is in fullscreen ?

For native MacOS apps i found this: https://stackoverflow.com/a/27397096/5838242

Where he saying:

window.level = Int(CGWindowLevelForKey(kCGMaximumWindowLevelKey))

On electron, i have a browser window:

mainWindow = new BrowserWindow({width: 1400, height: 50, resizable: false, alwaysOnTop: true, y: 0, x: 0, minimizable: false, title: 'CD App', frame: false, titleBarStyle: 'hidden', type: 'desktop' });

I know the 'type' parameter is the POINT, but this parameter have just two options:

On macOS, possible types are desktop, textured. The textured type adds metal gradient appearance (NSTexturedBackgroundWindowMask). The desktop type places the window at the desktop background window level (kCGDesktopWindowLevel - 1). Note that desktop window will not receive focus, keyboard or mouse events, but you can use globalShortcut to receive input sparingly.

So, any possibilities to do this thing ?

As of Electron 1.4.2 the setAlwaysOnTop() API takes an optional level parameter to adjust the window level, you'd use it like so:

mainWindow = new BrowserWindow({ ... });
mainWindow.setAlwaysOnTop(true, 'screen');

See the docs for all the possible values of the optional parameter, I'm not sure screen is the one you want in this case, you'll need to experiment.
