One of the Jira-projects in our organisation wishes to define who can access (view) specific Issues (or fields in an Issue). This is due to there potentially being sensitive information in the Issue Description field
Ideally all Issues that are added to a specific Epic called "Leads" should only be accessible to the Jira-projects administrators.
I have never used the Issue security screen before, as it is shared by all the Jira-projects in the organisation. I tried creating an automation rule, but it was too complicated for me to proceed.
We are using company-managed Jira-projects in our Jira Software (Premium)
