Help with push button

Hi how are things ! It took several days that I do not know how to do the following that I am going to comment on below. The idea is with an esp32 module and 3 LEDs, to simulate the bomb of a tactical shooter game in which, through the Blynk app, I would like one of the buttons (output pin gp32) to start flashing when you press and hold “only” 5 seconds. a blue led which, by means of several for loops, flashes in a certain way for 55 seconds. Once I know how to get that out, I think I’ll know how to do the rest. But as I say I have been several days in which I can not stop thinking how to do it Thanks in advance!!!

You need to use a combination of virtual pins, and BlynkTimer in countdown timer mode.
