My suggestion would be push notifcations to all users connected to your server as new content is added…
So i am relatively new to plex but as i digitise my collection i am getting fed up with family keep asking whats new i think this would be an awesome feature to have it would save all the hassles of them texts and keep repeating yourself over and over again
Like this?
You can only generally enable this on the server.
It’s up to each user in their mobile clients to select which notifications they want to see
Alternatively: encourage them to set up their Home Screen (on any Plex app) to include “recently added” hubs like this:
Search the Support Articles for “customizing” for more info.
And/or to use the Recommended tab for libraries instead of the Library tab.
And/Or to sort items in the Library view by Date Added.
Seriously, so many ways to get at that stuff 
i dont even see that option on my server
Notifications is a Plex Pass feature.
Early 2021 clean-up: implemented (Plex Pass feature)
