Currently, the JSM customers are unable to see Calendar events, on the knowledge base portal and in the Confluence page directly (page contains the Team Calendars macro), even if they are using Atlassian Accounts with the special permission to use Confluence as a unlicensed user, having the space and project linked, allowing any active user to see the space and permissions set.

We would like to suggest bringing back the ability for JSM customers to see the Team Calendars events again on the portal knowledge base articles.
If that is not possible to enable back the view for JSM customers on the portal articles, we would like to suggest to at least enable this view for JSM customers back for TC events on the spaces linked from JSM integration they are able to access configured for any active user to see it, to allow them (the unlicensed JSM customers) to view/edit at least the Calendar events directly on the Confluence pages.
