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

Start at the legacy router/router-extensions entry point referenced by the old imports and inspect how its mjs output exposes BackNavigationOptions, ExtendedNavigationBehaviorOptions, and ExtendedNavigationExtras. Done means those three types can be imported from the corresponding NS9 package path with Angular 21.
