Custom:button-card blinks when call service on

Hi

I made a custom:button-card of my thermostat that gives the temperature in different colors depending heat.
Also I made it possible when I toggle, the boiler turns on and off.
Now I want that my icon blinks every time the service that i toggle is on.
I’ve tried several search commands but can’t find a topic with the same question.
I am sorry but I am quite a nooby in this.
