How can I make the unity build window invisible?

Hi, I've been trying to make the window transparent for a long time but just can't make it work and I want to know if it is possible to just make the window overlay on top of everything whilst being invisible for example I want to have button that I can click on that is overlayed in front of my normal screen. Is it possible?

 

I'm not sure what exactly you're referring to.

Are you talking about this window?

https://docs.unity3d.com/Manual/BuildSettings.html

What are you trying to do with it? Why do you want it invisible?

Note... you can write your own editor script that builds stuff using the API:

No I mean the game's window like when I build my game I already made it invisible but I wanted it that I could make it invisible but still register button presses and UI button presses

 

I don't understand either. I try. Are you trying to create an app that records what the user does with his device? (like some kind of keylogger where you record all the touches?)

 

It is moments like this that I have my signature here on unity:

 

What OP is is saying (some interpretation involved):

OP is basically looking for a UI that allows him to place buttons in arbitrary positions on his desktop. Or over any other software or game for that matter. He wants to create a full-screen UI, which is (except for his buttons/ ui elements) completely transparent and passes all clicks, keypresses or other events that do not hit any of his buttons right through to the underlying software - be that some other game or his desktop.

So he effectively wants to create an overlay.
But i have no idea whether Unity is the right place to do so
