Group Master for Confluence
Your Jira instance is integrated with Confluence, with Jira acting as the primary manager of groups (having read/write permissions). Confluence will synchronize group data from Jira.
To manage groups in both Jira and Confluence simultaneously, use the Group Master for Confluence app. With the Application Link feature, you can easily connect Jira and Confluence, simplifying group management across both platforms.
