if its coming toward you, push the rudder where you want the nose to go.

Note- that every plane I've flown, inverted harrier requires holding left rudder as you are coming down to counter-act the right thrust (and torque) with right aileron if you give it throttle.

If its going by in front of you parallel to the runway, push the rudder in the direction its going, (for it to turn away).

BTW the latter is also a good way to enter an inverted rolling circle (happens a lot in unknowns) with the correct initial rudder input- without having to think about it.

Consider this the TOC tip of the day...
