Need help with blueprinting button prompts

Hey im a games design student still learning code and blueprinting i know what i want to do but i dont know how to translate it into blueprint, similar to the Telltale Walking dead series how it has a button prompt on screen when in ‘combat’ that if you dont press in time the walkers or other characters hit you i want to create a triggerbox area in which that similar button prompt would show up on screen as a form of a reaction speed test so multiple random button prompts that the player would need to press within 1-2 seconds of them showing up on screen before going to the next one. Any help is appreciated :slight_smile:
