All right! It seems that `decorateCookedElement` is what I needed (per @Arkshine note).

I also found this post that has some nice examples to filter on elements of interest:  
[How do we fire scripts after topic HTML is rendered in DOM? - dev - Discourse Meta](https://meta.discourse.org/t/how-do-we-fire-scripts-after-topic-html-is-rendered-in-dom/114701)

In particular, I found this very helpful:

```plaintext
$.fn.doSomething = function() {
  const targetElement = $(this).children("[data-theme-test]").length;
  if (!targetElement) return;

  // do your work
  
  return this;
};

api.decorateCooked($elem => $elem.doSomething(), { onlyStream: true });

```

Thank you!
