Finding a "Twitter-like" plugin to put inside a password protected page

Hi, I’m looking for a way to have a string of short messages inside of a Wordpress page. I don’t want a series of posts for such short messages. Instead, I’m looking for something a bit more like a Twitter feed, but it can’t be publicly accessible. This is for communication with employees on a Communication Page (password protected) on my WP website (ENFOLD theme).
This is just a way to update the team each day with new information that has an endless scroll so that they can read from the very beginning. I do not want it connected to any external social media. Is there something like this? I’ve searched microblogging plugins, but they are no longer being updated. Your thoughts are welcome.
