How do I use simple auth to login with Auth0 with universal login (redirection)?

I’m trying to implement login and permissions in an app I’m building. I took a look at and it seems it is more or less what I need. The problem is that I’m new to EmberJS and I only know Octane. Can I use this add-on on an Octane app? Also, I think this solves the login issue (setting up all the credentials) but how do I solve the permissions and RBAC? I’d like to restrict certain things from being edited or created depending on the JWT permissions.

Last, is it possible to solve all these issues with just ember-simple-auth? That one uses Octane and I think I’m able to read the documentation better than ember-simple-auth-auth0.
