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

Comienza por el punto de entrada heredado router/router-extensions al que hacen referencia los imports antiguos e inspecciona cómo su salida mjs expone BackNavigationOptions, ExtendedNavigationBehaviorOptions y ExtendedNavigationExtras. Se considera terminado cuando esos tres tipos se puedan importar desde la ruta de paquete NS9 correspondiente con Angular 21.
