Pausing Game but allowing a timer to still countdown?

I’m fairly new to blueprint and was curious as to how you would go about this after a button is clicked in a UMG rather than when a button is pressed and released.

Right now I have the ‘P’ button bring up a pause menu and then within that pause menu is a resume button. When the resume button is clicked is when I want the 3 second countdown to start. However I don’t know how to call the button clicked in the UMG in my character blueprint so that the timer correctly knows when to start. Any ideas?

Thanks!
