ESPHome FastLed on_boot effect

Hello guys,
I would like to ask someone advise how to make specific effect on my addressable Light strip when I turn it on. Now no matter what I do it always just turns on and after that I can choose effect. Probably because I am new to ESPHome and hassio for me all information in ESPHome FastLED website is not clear… I tried many different ways but still cannot find how to do that.
For example I want that when I press “ON” Leds would turn on 1by1 till the end, something similar to that “wipe” action.
