Hello Anna,
Thanks for writing to us.
In the latest version of X theme, It has been available under “Settings” submenu of X.
You can always manage permission at Admin > X or Pro > Settings > Permissions. But that’s just allowing capabilities to a certain role, and it’s not where you assign the role to a user.
If you already have an existing role assigned to a specific user, then yes, you can go ahead allow cornerstone’s capabilities in that permission setting area.
Now, if what you’re referring is role management, then you’ll still need a plugin that will allow you to manage it, and you can edit each user at Admin > Users to assign that specific role.
Please have a look at the screenshot given below
Thanks
