We have a set of people who have access to Confluence but not Jira, so they do have Atlassian accounts. We want to give them some *very* basic transparency about what items are already in a project backlog so that they can know that their bug or feature request is already a known item.
I was hoping that I could create a Confluence page that would embed the backlog with the Jira Issue Filters Macro - all the users would need to do is scroll through the list, they don't need to click through to see individual issues or take any action on them in Jira itself.
