How do Autentification connection and manage session with "angular-oauth2-oidc"?

I have client application Agular13 and Open id connect authentication server, in implicit flow mode.

So I used the "angular-oauth2-oidc" and "angular-oauth2-oidc-jwks" library to do this.

Actually I manage to connect and redirect to my home page, But I can't get the session information which is currently in the local storage, and I would also like to secure the pages by authentication and by role.

But the first time I only have the user information then I can't access it, I get an empty object while I still have a token in the local starage. And i have error "token_error" -> "login_required". But the token should still be valid because it is set for 8h

  private jwtHelper: JwtHelperService = new JwtHelperService();

  private _decodedAccessToken: any;
  private _decodedIDToken: any;

    return this._decodedAccessToken;

    private oauthService: OAuthService,

      this.oauthService.configure(this.authConfig);

      this.oauthService.tokenValidationHandler = new JwksValidationHandler();

      this.oauthService.events
        .pipe(filter((e: any) => e.type === "token_received"))
        .subscribe(({ type }) => {

import { AuthConfig, OAuthModule, OAuthStorage } from "angular-oauth2-oidc"
import { InitialAuthService } from "./initial-auth.service";
import { environment } from "../../environments/environment";

const configAuthZero: AuthConfig = environment.idp;

export function storageFactory(): OAuthStorage {
  return localStorage
}

@NgModule({
  imports: [OAuthModule.forRoot()],
  providers: [
    InitialAuthService,
    { provide: AuthConfig, useValue: configAuthZero },
    { provide: OAuthStorage, useFactory: storageFactory },
    {
      provide: APP_INITIALIZER,
      useFactory: (initialAuthService: InitialAuthService) => () =>
        initialAuthService.initAuth(),

export class AuthModule { }

 issuer: issuer,
    redirectUri: redirectURL,
    clientId: 'implicit',
    scope: "openid",
    showDebugInformation: true,
    dummyClientSecret: secret,
    logoutUrl: logoutUrl+clientid,
    skipIssuerCheck:true,

My bind code seems to fill the localstorage but I don't seem to manage or retrieve the information.

How do that?
