Why I can't see a security tab in the Workspaces section of GeoServer 2.17.2?

I installed the last version of GeoServer. According to GeoServer documentation, I should be able to modify the security of the workspace with a dedicated tab on Edit Workspace, when I click on a workspace name. However, as you can see in the snapshot, my GeoServer is not showing the security tab. How can I enable this tab?

In GeoServer documentation, Edit Workspace clearly has a security tab
