Is there a decorator in django to set access permissions to the required function in the View?

Question

Django

Good afternoon,
I understand FW Django, can you tell me if it is possible to add a decorator above each path () in VIew.py and indicate in it the name of the group of users who are allowed access?
I created a super user, went to the admin panel, but did not understand how I can set the necessary rights for my user to access only certain methods. In the @login_required decorator, which is used in Models, as far as I understand, we cannot pass the role name to users who are allowed access to the corresponding method.
PS: I apologize if the question is technically not quite literate.
Example of my Urls.py:

path('accueil', views.connexion , name='connexion'),
    path('accueilEmploye', views.connexionEmploye , name='connexion'),
    path('deconnexion', views.deconnexion, name='deconnexion'),
    path('liste_projets/<int:id>', views.list_projet), #client
    path('liste_tickets/<int:id_projet>', views.list_tickets), #client
    path('ajout_tickets/<int:id_ticket>', views.add_ticket), #client
    path('liste_demande', views.list_projets_clients), 
    path('affectation_ticket/<int:id_projet>', views.liste_tickets_clients),
    path('liste_tickets_assigne/<int:id_ticket>', views.liste_tickets_assigne),

    path('detail_tickets_assigne/<int:id_ticket>', views.detail_ticket_assigne),

Here's the Models.py my goal is to restrict some users' access to not some methods

If I understand the author correctly, then you need @permission_required
