I'm sure this is a really stupid question, but I cannot find an answer anywhere! I have installed a new plugin to Confluence (v5.8.13) using UPM and I can see it installed and enabled successfully in 'Manage add-ons'. There's no configuration that needs doing (it's a Calendar-style plugin).
What I cannot tell is how an end-user references that plugin from within a newly created page, actually creates himself a calendar (in this instance, but it could be any plugin) on his page? How do you reference add-ons/plugins for actual use? I can't believe that's not in the Confluence help anywhere, or if it is, that I've managed to miss it!
