Can someone explain to me why you aren’t supposed to breastfeed after receiving AirSculpt?

Can someone explain to me why you aren’t supposed to breastfeed after receiving air sculpt? I don’t understand if the rationale is because “your body may still change” or there’s some inherent risk to the baby. The latter doesn’t make sense to me physiologically, given as I understand it’s just laughing gas given during the procedure. Would I be safe to nurse a baby 1-2 times a day after the procedure? Or even pump and dump if necessary?
