Stalking Leonin has a triggered ability that lets you secretly choose an opponent and an activated ability that has you reveal the opponent as a cost.

My confusion stems from getting multiple ETB trigger via say Panharmonicon.

I'm assuming you can choose both the same/different opponents for the triggers, but how does revealing the chosen player work? Do you reveal all players chosen and exile an attacking creature controlled by one of them? Do you reveal one of the players chosen and exile one of their creatures leaving a secretly chosen opponent to choose later? Something else entirely?
