My types are gone

Hello together,
I am just trying to migrate to NS9 and Angular 21. However, unfortunately it seems like some types I need are gone. Would it be possible to add them to the exports? Seems like the mjs files do not export them
Here the relevant imports from the old package
import {
BackNavigationOptions,
ExtendedNavigationBehaviorOptions,
ExtendedNavigationExtras
} from '@nativescript/angular/lib/legacy/router/router-extensions';

ns --version
9.0.2

Inizia dal punto di ingresso legacy router/router-extensions referenziato dai vecchi import e verifica in che modo il relativo output mjs espone BackNavigationOptions, ExtendedNavigationBehaviorOptions ed ExtendedNavigationExtras. Il lavoro è completato quando questi tre tipi possono essere importati dal corrispondente percorso del package NS9 con Angular 21.
