I can prevent user for clicking other button component that route to outside current component using overlay. But if user clicking back browser button, the tour is still running. so i use navigation guard and search the classname like this ```js beforeRouteLeave (to, from, next) { const tourOverlay = document.getElementsByClassName('shepherd-modal-is-visible')[0] const tourStep = document.getElementsByClassName('shepherd-enabled')[0] if (tourOverlay && tourStep) { tourOverlay.remove() tourStep.tourStep() } next() } ``` Is there a best practice to achieve this?
