The latest version of "Confluence Server for Slack (Official)" was released a few days and contains support for a new slash command. Inside my Slack workspace, the new slash command functions (it's `/conflucne_server search <query>`) but I had to guess what it was, since the exact syntax isn't documented anywhere and doesn't autocomplete.
How does the Slack side of these integrations get updated, when its code is deployed globally, but confluence server app updates are deployed locally?
