I don’t think anyone would recommend getting underneath a car that is supported solely by a jack.
Using a jack is fine but make sure you get a good pair of stands with the right load rating to go with it.
Mind you with a lowered car, you may find yourself needing some planks of wood to drive up onto, so the jack will clear the crossmember.

Heard some bad stories about ramps where they fly out or get jammed under the car when trying to drive the car up onto them.
