Is this a premium functionality

System Information
  • Strapi Version: 4.4.1

I have created some plugins and I am trying to add the permissions for Editor, Author and Super Admin. I can’t seem to make the plugin appear in this area (from the screenshot). Also the ones that exist don’t seem to be clickable. Is this a premium functionality?

This links says something related to that but it is not clear about the plugins I create.

Configure Administrator Roles - Strapi User Guide

if it is indeed a premium feature, the author, editor and super admin fields can only be edited with this feature, however your plugin is free.
