"Close Application" System Action?

Hi.

I used to use Construct Classic and then I bought C3. When making my "exit" button in CC, there was a System action in the event sheet to close the application when the mouse clicks the button and BOOM! It closed the application and it was so easy. But C3 doesn't have that System action to close the application. I just bought C3 recently, so can you help me?

Thanks in advance.
