I´m not sure about how to made it, that´s why Im asking here, maybe one you can help me (plz, it has been stuck in my head for a while

)
Idk if is a volume automation, sidechain, LFO, I tried to do it with my knowledge but is not enough

Here some examples:
min 1:10
min 2:59 and 3:02
min 1:33
Its like a volume up and down automation I'm not sure how to describe it but sounds like that (maybe attack automation?)
