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

objects to inject it easily without container access.
In the future we should also deprecate `this.appEvents` without an
explicit injection too.
