[F7-Vue] App/View back event

Hi everyone,
I have an issue with views, router, and navbar.
My app has multiple views as tabs (like Spotify, to understand better) and I am creating a new view where I redirect the user when he clicks on the notification. The issue appears when the user needs to go back to the previous view. Using the “android back button”, I can manage the issue, but I can’t when he click on the nav-left button. I tried with routesBeforeLeave but if the page is the only one in router history he doesn’t work. So, there is something that helps me to know if the user has clicked on nav-left that works in every route without emitting manually a custom event for every page?

I hope I have explained the situation and my problem in an understandable way.
Thanks
