Posts are limited to 10 when we call it by Category List

[zexperto]

when you use the query "mpBlogCategories" and we query the posts, the number of posts we are getting is only 10, you can check this class
Class: \Mageplaza\BlogGraphQl\Model\Resolver\Resolver\Post:: resolve

public function resolve(Field $field, $context, ResolveInfo $info, array $value = null, array $args = null)
{
$category = $value['model'];
$postCollection = $category->getSelectedPostsCollection();
$searchCriteria = $this->searchCriteriaBuilder->build('posts', $args);
$searchCriteria->setCurrentPage(1);
$searchCriteria->setPageSize(10);
$searchResult = $this->filterQuery->getResult($searchCriteria, 'post', $postCollection);

return [
    'total_count' => $searchResult->getTotalCount(),
    'items'       => $searchResult->getItemsSearchResult()
]

}

I believe we should get all or we use PageSize
