As always, the new interceptor has to be added in the app.module.shared.ts file right below the existing one:

[...]

import { AuthInterceptor } from './services/auth.interceptor';
import { AuthResponseInterceptor } from './services/auth.response.interceptor';

[...]

    providers: [
        AuthService,
        {
            provide: HTTP_INTERCEPTORS,
            useClass: AuthInterceptor,
            multi: true
        },
        {
            provide: HTTP_INTERCEPTORS,
            useClass: AuthResponseInterceptor,
            multi: true
        }
    ]
