I have rolled my own using Angular 7 frontend + nebular and SS 5.3. The implementation is a customized version of the ORM Lite Auth Repo (separate plugin) using custom roles, permissions + based content access. Then all font end access is based on JWT role based access. The admin screens manage all users, permissions and roles.
I can drop you screenshots (on email) of this if you wish.
