When the “footer” is rendered in Discourse, the app sends an “event”

The event is `inserted-custom-html:footer`

You can use that event to update your footer content like so

```javascript
api.onAppEvent("inserted-custom-html:footer", () => {
  // add your JS here
});

```

There’s a few more details [here.](https://meta.discourse.org/t/javascripts-targeting-the-footer-doesnt-work-after-page-transitions/180012/4)

This should work for what you’re trying to achieve. If it doesn’t, let me know - and post the code you’re using.
