How to use the apollo-server-errors.PersistedQueryNotFoundError function in apollo-server-errors

// PrefixingKeyValueCache yet.
    if (!(persistedQueryCache instanceof PrefixingKeyValueCache)) {
      persistedQueryCache = new PrefixingKeyValueCache(
        persistedQueryCache,
        APQ_CACHE_PREFIX,
      );
    }

    queryHash = extensions.persistedQuery.sha256Hash;

    if (query === undefined) {
      query = await persistedQueryCache.get(queryHash);
      if (query) {
        metrics.persistedQueryHit = true;
      } else {
        throw new PersistedQueryNotFoundError();
      }
    } else {
      const computedQueryHash = computeQueryHash(query);

      if (queryHash !== computedQueryHash) {
        throw new InvalidGraphQLRequestError(
          'provided sha does not match query',
        );
      }

      // We won't write to the persisted query cache until later.
      // Defering the writing gives plugins the ability to "win" from use of
      // the cache, but also have their say in whether or not the cache is
      // written to (by interrupting the request with an error).
      metrics.persistedQueryRegister = true;
    }
