I used Fluid to create a Gmail app that would show my unread mail count in the dock. After upgrading to Catalina, the app no longer shows a badge in the dock, and I believe this is because it doesn't have permission to do so. But if I go into the Notification preferences, neither Fluid nor my Gmail app appear, so I can't grant them permission via the UI
I've reported this to the maintainer of Fluid, but while I wait, is there any other way for me to grant these permissions? Perhaps there's some command I can run from the terminal, or a plist somewhere that I could edit, to grant my app permission to show badges on its icon?
