By default, each user can view the Herzum web panels on the issue view screen.
The Permission Administration screen allows you to control who can view the Herzum Quick actions and the Herzum Quick Links panels.
E.g. Only Project Lead can view the Quick Actions panel and only Developers can view the Quick links panel.
Furthermore, you can hide the panels entirely, by choosing to show them on the selected projects exclusively.
E.g. You need that Quick links panel is displayed on the source Projects solely.
Following, you can review how to manage these settings.
