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

古い imports で参照されている legacy の router/router-extensions エントリーポイントから開始し、その mjs 出力が BackNavigationOptions、ExtendedNavigationBehaviorOptions、ExtendedNavigationExtras をどのように公開しているかを確認します。これら 3 つの型を Angular 21 で対応する NS9 パッケージパスから import できれば完了です。
