Signal on timeline to exit application?

I am sure this is possible… Can someone explain how to do this? New to timeline/signals. I assume a script to exit the application and then how do I ‘tie’ the script to the signal event? Thanks for your time.

You have your script withe Code to quit the application on a gamobject in a public function, add a SignalReceiver component to the object.
Choose the singal you used in your timeline and asigne the public function in the event trigger of the SignalReceiver .
