Cannot get articles in specified category

The API docs indicate you should be able to GET /api/v2/help_center/categories/{category_id}/articles however I can't find a way to do this in this library. I would expect to find it in $zendeskHttpClient->helpCenter->categories($category_id)->articles()->iterator() but that doesn't exist. I tried $zendeskHttpClient->helpCenter->categories($category_id)->sections()->articles()->iterator() which gives all articles.

I think Zendesk\API\Resources\HelpCenter\Articles needs to be updated with something like (I tried it and it seems to work in my case, but I don't know what I'm missing)

    public function getRoute($name, array $params = [])
    {
        $lastChained = $this->getLatestChainedParameter();
        $params = $this->addChainedParametersToParams($params, [
            'section_id' => Sections::class,
        ]);
        if (empty($lastChained) || $name !== 'findAll') {
            return $this->localesGetRoute($name, $params);
        } else {
            $chainedResourceName = array_keys($lastChained)[0];
            $id = $lastChained[$chainedResourceName];
            if ($chainedResourceName === Sections::class) {
                $locales = $this->getLocale();
                if ($locales) {
                    return "{$this->prefix}{$locales}/sections/$id/articles.json";
                } else {
                    return "{$this->prefix}sections/$id/articles.json";
                }

            // This block is added:
            } elseif ($chainedResourceName === Categories::class) {
                $locales = $this->getLocale();
                if ($locales) {
                    return "{$this->prefix}{$locales}/categories/$id/articles.json";
                } else {
                    return "{$this->prefix}categories/$id/articles.json";
                }

            } else {
                return $this->localesGetRoute($name, $params);
            }
        }
    }

Start in Zendesk\API\Resources\HelpCenter\Articles::getRoute and compare the existing section-scoped article route with the category chain described in the issue. Verify that the category iterator requests the category-specific articles endpoint and returns only that category's articles.
