does anyone know any plugin or code that warns the user that there is a new post for him to reload the page, after I publish a new post?

Example I’m on my panel and publish a post.

User is at the site home and receives notice that a new post has been published and to reload the page.

I don’t want web notification, for example one signal, I want a message if possible over the post area that appears.

Since already I thank everyone.
