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

Beginne beim in den alten Imports referenzierten Legacy-Einstiegspunkt router/router-extensions und prüfe, wie dessen mjs-Ausgabe BackNavigationOptions, ExtendedNavigationBehaviorOptions und ExtendedNavigationExtras bereitstellt. Fertig ist die Aufgabe, wenn diese drei Typen aus dem entsprechenden NS9-Paketpfad mit Angular 21 importiert werden können.
