Owl Carousel 2 - Getting Active Items

I have an Owl Carousel 2 that's being generated by a WordPress theme and I've set up some custom scripts similar to this:

owl.on('changed.owl.carousel', function() {

    activeEls = $('.owl-item.active');

    setCarouselCaption( activeEls[1] ); 

});

This places the image caption of the middle image below the carousel in a full-width container.

The issue I'm having is, when I assign the active items to activeEls - it's grabbing the active items BEFORE the click - rather than after.

Is there any way to wait for the Owl Carousel to update the active items and THEN assign those to activeEls?

OR - is there any way to detect whether the Previous or the Next button was clicked? Right now, I'm only able to detect a change but not which change.

Another suggestion, without using setTimeout:

owl.on('changed.owl.carousel', function(event) {
  let activeElement = $('.owl-carousel .owl-item.active');
  if ($(activeElement).next().length > 0) {
    console.log($(activeElement).next());
  }
});

A .setTimeout() as short as 1ms does the trick here.

$(document).ready(function(){
  var owl = $('.owl-carousel').owlCarousel({
    loop:true,
    margin:10,
    nav:true,
    items:3
  });
  
  owl.on('changed.owl.carousel', function(event) {
    setTimeout(function(){
      var activeEls = $('.owl-item.active').eq(1); // .eq(1) to get the "middle image out of 3 actives"
      setCarouselCaption( activeEls ); 
    },1);
  });

  function setCarouselCaption(el){
    $(".owl-item").removeClass("target");
    el.addClass("target");
  }

});  // Ready
.target{
  border-bottom:1px solid red;
}
