withFeature() does not exist on @ngrx/signals - angular 19.2.1

Hi everyone,
i am trying to use the withFeature() to connect an existing store to a custom storeFeature().
but when trying to reference from @ngrx/signals it could not be resolved...

I tried to follow the docs example like so:

import { computed, Signal } from '@angular/core';
import { patchState, signalStore, signalStoreFeature, withComputed, withFeature, withMethods, withState } from '@ngrx/signals';
import { withEntities } from '@ngrx/signals/entities';

export function withBooksFilter(books: Signal<Book[]>) {
  return signalStoreFeature(
    withState({ query: '' }),
    withComputed(({ query }) => ({
      filteredBooks: computed(() =>
        books().filter((b) => b.name.includes(query()))
      ),
    })),
    withMethods((store) => ({
      setQuery(query: string): void {
        patchState(store, { query });
      },
    })),
)};

export const BooksStore = signalStore(
  withEntities<Book>(),
  withFeature(({ entities }) =>
    withBooksFilter(entities)
  ),
);

but with no luck

were can i found withFeature()?

@BarakDabach, you need to update @ngrx/signals to the latest version, which is 19.1. Just run ng update and it should show up.
