Or they already have that, but it's badly designed, bloated, or doesn't have employees assigned to it.

> some kind of admin panel where employees can easily CRUD some updates

In my experience this is usually the crux. That software always rots, and needs whatever (minimal) on-ramping for employees, as well as access management.

If I could wave a wand at those solutions I'd stop fighting the user and let them post to Twitter or wherever, and just have a public facing page pull those posts as updates for consumers outside of whatever walled garden they originate from.

Access management is already a problem - just maybe they haven’t run into it. What happens when the employee who has the twitter password leaves? (This is France so the only way is probably retirement).

A bespoke system with an interface similar to twitter sounds like it’d be a suitable solution. And I bet it can be vibe coded in 5 minutes.

And when it rots, some enterprising employee says: hey, why don't I just make a foobar account and post there? That would work so much better.
