When you have finished drafting a report, you can publish the report, which means all roles have read-only access to the report to prevent other users from making changes. If you unpublish a report, that access is reverted. Publish/unpublish does not revert any read/write access that you grant to a specific role.
Navigate to the Threat Intel Reports table and click the Name of the report you want to share.
From the Access section, Publish the report.
Once published, anyone who you give the report link to can see the report (provided they have access to your Cortex XSOAR environment). To remove read-only access, Unpublish the report.
