How do I make my game fullscreen?

Hello.

I have recently exported my game via nw.js, but I have noticed that it is not fullscreen, nor can you close it using the escape key or pressing an 'X' button. I am also unable to find any End/Close application actions, and I would love some help.

I am running Construct 2 r209.

Thank you.

add object "browser"

fullscreen: action browser request fullscreen

quit/exit: action browser.close

Thank you, that worked!!

greetings sir, I want to ask. My Apk has been successful, and the admob is also good. But for full screen, why is it so difficult, after exporting, sometimes the bottom is over, sometimes the sides are over. Is there a solution, friend? Thank you in advance.
