Can't access private method from within SignalStore

[hafnerpw]

Which @ngrx/* package(s) are the source of the bug?

signals

Minimal reproduction of the bug/regression with instructions

From other methods and hooks inside the signal-store I want to access private methods of it. The Documentation is not providing an example for it https://ngrx.io/guide/signals/signal-store/private-store-members So I tried it like this:

export const ComponentMetaInfoStore = signalStore(
  withState<ComponentMetaInfoState>(initialState),
  withMethods(
    (
      store,
      componentsService = inject(ComponentControllerService)
    ) => ({
      _addComponent: (component: ComponentDtoV2) => {
        if (store.components().find((c) => c.id === component.id)) {
          return;
        }
        patchState(store, { components: [...store.components(), component] });
      },
      addComponent: rxMethod<CreateComponentDtoV2>(
        pipe(
          switchMap((component) => componentsService.create({ body: component })),
          tapResponse({
            next: (component) => {
              _addComponent(component);
            },
            error: (error: HttpErrorResponse) => {
              patchState(store, { error: error.message });
            }
          })
        )
      )
    })
  ),
  withHooks((store, eventDispatcher = inject(EventDispatcherService)) => {
    return {
      onInit() {
        eventDispatcher
          .on<ComponentDtoV2>(BaseEventType.CREATE)
          .subscribe((component) => {
            _addComponent(component);
          });
      }
    };
  })
);

other access with this._addComponent or store._addComponent is not possible either.

Expected behavior

private signal store methods should be accessible from within the store. Also the documentation should show an example on how to use it.
