Retrieving roles for role based navigation

Hi there !
I’m trying to make a role based navigation, I followed all the getting started, and got a bit further too with setting rule but I really don’t find anything about how achieve my purpose.

I’m working with Angular 12, following the getting started, I have an authentication working and I can get the users profile where the role is present.

  "": [
  "nickname": "admin",
  "name": "",
  "picture": "",
  "updated_at": "2021-08-18T18:49:28.033Z",
  "email": "",
  "email_verified": true,
  "sub": "auth0|60fef57f0dde01006890f396"

How do I get the role ?
