Publication interaction behavior

## Likes The like button should save the liked article to the database. The liked content should then appear on the profile page you already made, where users can see their liked articles and news. Hopefully, we can add liked Deep Dives and Exclusives later, but those sections don't have the introduction needed for this yet. I already talked to the Deep Dives team about it, but I don't think they'll do anything about it anytime soon... ## Share The share button should work the same way as the one on the News and the comment section. It opens a pop-up with different sharing options. I think you guys implemented this a long time ago, so I'm not sure if it still exists, but we can reuse it if it's still available. ## Join The Join button should invite users to join our Discord server. However, instead of just linking directly to Discord, we can reuse the same pop-up CTA element that's already on the homepage.
