AngularFire Function, ignore Region setting

[Biokimist]

When using Angular Fire 19.0.0 - Angular 19.1.7 - Firebase function 6.3.2
Function.region are ignore with httpsCallable

appConfig

export const appConfig: ApplicationConfig = {
  providers: [
    provideRouter(routes),
    provideHttpClient(withInterceptorsFromDi()),
    provideAnimationsAsync(),
    provideFirebaseApp(() => initializeApp(environment.firebase)),
    provideAuth(() => {
      const auth: Auth = getAuth(inject(FirebaseApp));
      if (environment.useEmulators) {
        connectAuthEmulator(auth, `http://localhost:${environment.emulatorPorts.auth}`, { disableWarnings: true });
      }
      return auth;
    }),
    provideFirestore(() => {
      const firestore: Firestore = initializeFirestore(inject(FirebaseApp),{
        localCache: persistentLocalCache(),
      });

      if (environment.useEmulators) {
        connectFirestoreEmulator(firestore, '127.0.0.1', environment.emulatorPorts.firestore);
      }

      return firestore;
    }),
    provideFunctions(() => {
      const functions: Functions = getFunctions(inject(FirebaseApp), 'europe-west3');

      if (environment.useEmulators) {
        connectFunctionsEmulator(functions, '127.0.0.1', environment.emulatorPorts.functions);
      }

      return functions;
    }),
    provideStorage(() => {
      const storage = getStorage(inject(FirebaseApp));
      if (environment.useEmulators) {
        connectStorageEmulator(storage, '127.0.0.1', environment.emulatorPorts.storage);
      }
      return storage;
    }),
    [...]
  ],
};

   getFunctions(inject(FirebaseApp), 'europe-west3');

This should link Functions to 'europe-west3'

Usage in service

import {httpsCallable, Functions, HttpsCallableResult} from '@angular/fire/functions';

@Injectable({
  providedIn: 'root'
})
export class MyService {
    constructor(private functions: Functions){}

    public onCall (){
      const doSomething = httpsCallable(this.functions, 'onCallDoSomething');
      const response: HttpsCallableResult<any> = await doSomething();
    }
}

when onCall(), i get this error:

    POST https://us-central1-rentwave-prod.cloudfunctions.net/onCallDoSomething net::ERR_FAILED

us-central1 is the default region.
httpsCallable, doesn't apply region settings and target the wrong region.
Or I may have misunderstood the way to build appConfig

I tried to override the region by adding just before the httpsCallable; With no luck

   this.functions.region = "europe-west3"

IMPACT:

firebase httpsFunction are unavailable if not on us-central1
