This is to streamline the new user narrative. only works when creating the bookmark, if editing/deleting the modal is shown. This is done via the plugin initializer.
AppEvents was always a service object in disguise, so we should move it
to the correct place in the application. Doing this allows other service
objects to inject it easily without container access.
In the future we should also deprecate `this.appEvents` without an
explicit injection too.
