I’d report it to AA. Like low level behaviors that may cause offense or characteristics that might affect work performance, resulting reports are usually documented and may be brought forward if they reach a certain volume or are frequent. In this instance it’s unlikely to result in any discipline (nor would I want any disciplinary action), but the employee may be advised or counseled so less scent is used during work hours. (This would be typical in most large companies with professional HR offices, in my experience.)
