The timeline has been updated to use regular Ember/Glimmer components rather than our custom ‘widget’ system, so I’m afraid `decorateWidget` won’t work there any more.

Instead, you’ll need to use a [Plugin Outlet](https://meta.discourse.org/t/using-plugin-outlet-connectors-from-a-theme-or-plugin/32727). Right now we have these two:

But if they don’t work for your use case please let us know and we’re happy to look at introducing new ones.
