That was the one :) On Phil's lab I watched "KiCad STM32 + USB + Buck Converter PCB Design and JLCPCB Assembly" which is even more in depth and longer...but it missed some tricks which Contextual Electronics had (such as drawing one wire through components in a voltage divider to link all of them). I recommend watching both...and probably more.
