On the Vision Pro, tap your index finger and thumb together. Maybe they could add other features from just your face though for other platforms, wiggling nose, raise eyebrows, stick out tong, blow a raspberry? That or they add voice commands, "open", "select" and such. I suppose ultimately in spatial computing with voice interface and eye tracking the concept of a "click" may die.
