How to force NSWindow to be in front of each application? Even fullscreen apps

I have NSWindowthat I would like to have it in front of everything (every computer application, full-screen applications, etc.). Even if I am in the background application, it NSWindowdoes not fit the background. And it NSWindowshould follow the user's screen if, for example, the user switches the desktop to desktop2, etc. .... How can I do this?
Thank!
