Wordpress: editorial comments?

Question

WordPress

I want to make it possible for admins to write editorial comments to authors, and the second to respond to them + so that in the admin panel there are notifications about comments to both the admin and the authors and not by e-mail. I found the Edit Flow
plugin and it’s great, but I didn’t find a notification method in the admin panel there, there is a possibility for notifications, but as I understand they go to the mail, but I don’t want this, I want to do notifications only in the admin panel ... Please share your experience .
