Can someone please tell me what button or buttons activates traps in LoV on PS4.

I asked this back in February and no one could answer it. I can't clear challenge 9 without knowing this. The rules for PS4 only tell you how to execute action, while the rules for PC users tell you how to execute action and how to execute trap. I've tried every button and button combination, but nothing works. I shouldn't need to buy a kb and mouse for PS4 to activate trap as you would think SE would include a way for controller players to activate a trap.

EDIT: SE really should change the wording in the rules. The rules say to select execute trap in the minion hotbar, but there never was an execute trap option that appears in the minion hotbar. Well I just found out you manually need to move the selector out of the minion hotbar to the turqoise activate trap circle, which is not in the minion hotbar.
