In my case it's Caprine (Facebook messenger app). In caprine.desktop I added X-GNOME-UsesNotifications=true and Categories=GNOME;GTK;Network;Chat;, but I only get notifications in the notification center and bubble notifications, without a red badge like there is one in Mail or AppCenter.
This might be an answer, but I'm not sure if it still applies to Juno: How do I enable notification badges on plank?

  • It mind sound funny and irrelevant, I was also looking into this. I could have offered a bounty on this if you didn't!

I'm pretty sure you've linked to the right answer: Plank's badges are separate from notification center, and they have to be implemented separately. However, you might consider adding a wishlist item on the launchpad.
