This is a Component, handilly, so you would want to override this method `didInsertElement()` in your initializer.

Example:

```plaintext
withPluginApi('0.8.12', (api) => {

      api.modifyClass('component:load-more'

```

from here [https://github.com/paviliondev/discourse-topic-previews/blob/master/assets/javascripts/discourse/initializers/preview-edits.js.es6](https://github.com/paviliondev/discourse-topic-previews/blob/master/assets/javascripts/discourse/initializers/preview-edits.js.es6)

If you are lucky you can just call `this._super();` and append your additional logic at the end.
