customize transitions with scripts in Premiere pro

I added transitions in this way.

  app.project.sequences[0].videoTracks[0];
    var transition = "Push";
    app.enableQE();
    var qeSequence = qe.project.getActiveSequence(0);
    var vanillaSequence = app.project.activeSequence;
    var qeTrackOne = qeSequence.getVideoTrackAt(0);
    var vanillaTrackOne = vanillaSequence.videoTracks[0];
    var transitionToApply = qe.project.getVideoTransitionByName(transition);
    var item = qeTrackOne.getItemAt(0);
    var item1 = qeTrackOne.getItemAt(1);
    item.addTransition(transitionToApply, false, '00;00;00;08');
    item1.addTransition(transitionToApply, false, '00;00;00;08');

I want to access Effect Controls and select "Reverse" select true.
is there a way to access the Effect Controls of a push transition with a script?

Thank you very much.
