add an exit button.

Is your feature request related to a problem? Please describe.
When installing a game theres a pop up giving the option to import or to install the game but not to exit the installation, it is very unclear that you need to click outside the pop up for it to stop the installer

Describe the solution you'd like
the solution is adding an X button to the pop up so its easy to know where you need to click to exit it.

Describe alternatives you've considered
add a third button to the button on the left side preferably that says cancel or exit

Additional context
very rough example of the first solution:
