Show/hide menus in sidebars depending on the user roles (Laravel/Spatie)

I have 2 roles in my application which are admin and former. For information, the permissions are OK also.

Now, my problem is that if the user Former is connected. He can see the rubric "Admin" , is it possible to keep only the rubric formers?

Do know you the modification on my code please? I am hesitating between Controller or Middleware?
