Progressbar for duration

[alisson-acioli]

I would like to give the idea of creating a progress bar just below the notification box that fills according to its duration. There is a Toast that I use for Vue 3 that has this feature and I think it's cool because for those who see it, they know that that notification won't stay there forever, so whenever the person sees that notification on the site they know how long it will disappear.

It may seem like a "beast" resource but I believe it can help one or another user of a site.
