At the moment, Confluence is currently not allowed to use system apps as described on the Confluence guest's documentation: https://support.atlassian.com/confluence-cloud/docs/what-can-guests-see-and-do-on-confluence/.

There are some use cases that would benefit a lot if guests were also allowed to use Confluence system apps including the following:

• Confluence analytics

• Space analytics

• Team calendars

• Confluence Questions
