Modify Custom Taxonomy slug with CPT slug - url-rewriting

Question

Hi please check my requirement bellow.
First of all, I have registered a CPT "directory" with a slug name "directory". Also, I have registered a custom taxonomy "business_category". I want to below permalink structure.
CPT Archive link: www.domain.com/directory/
Taxonomy link: www.domain.com/directory/category/TAXONOMY_NAME/
CPT Single Page: www.domain.com/directory/POST_NAME
So, I have used the Below code.
public function __construct( $plugin_name, $version ) {
$this->plugin_name = $plugin_name;
$this->version = $version;
$this->PT = 'cc-directory';
$this->name = 'Directory';
$this->singular_name = 'Directory';
$this->slug = 'directory';
}
public function register_post_type() {
// Get supported features for Directory post type
$supports = apply_filters('cc_directory_supports', array('editor', 'title','thumbnail'));
$labels = array(
'name' => $this->name,
'singular_name' => $this->singular_name,
'add_new' => 'Add New',
'add_new_item' => 'Add New ' . $this->singular_name,
'edit_item' => 'Edit ' . $this->singular_name,
'new_item' => 'New ' . $this->singular_name,
'all_items' => 'All ' . $this->name,
'view_item' => 'View ' . $this->name,
'search_items' => 'Search ' . $this->name,
'not_found' => 'No ' . strtolower($this->name) . ' found',
'not_found_in_trash' => 'No ' . strtolower($this->name) . ' found in Trash',
'parent_item_colon' => '',
'menu_name' => $this->name
);
$args = array(
'labels' => $labels,
'public' => true,
'publicly_queryable' => true,
'show_ui' => true,
'show_in_menu' => true,
'query_var' => true,
'rewrite' => array( 'slug' => $this->slug ),
'capability_type' => 'post',
'has_archive' => true,
'hierarchical' => true,
'menu_position' => 11,
'menu_icon' => 'dashicons-book',
'supports' => $supports,
'yarpp_support' => true
);
register_post_type( $this->PT, $args );
$plural_label = 'Categories';
$singular_label = 'Category';
register_taxonomy(
'business_category',
$this->PT,
array(
'label' => $plural_label,
'labels' => array(
'name' => $plural_label,
'singular_name' => $singular_label,
'all_items' => sprintf(__('All %s', 'claritycloud-directory'), $plural_label),
'edit_item' => sprintf(__('Edit %s', 'claritycloud-directory'), $singular_label),
'view_item' => sprintf(__('View %s', 'claritycloud-directory'), $singular_label),
'update_item' => sprintf(__('Update %s', 'claritycloud-directory'), $singular_label),
'add_new_item' => sprintf(__('Add New %s', 'claritycloud-directory'), $singular_label),
'new_item_name' => sprintf(__('New %s Name', 'claritycloud-directory'), $singular_label),
'popular_items' => sprintf(__('Popular %s', 'claritycloud-directory'), $plural_label),
'search_items' => sprintf(__('Search %s', 'claritycloud-directory'), $plural_label),
),
'public' => true,
'show_ui' => true,
'show_in_rest' => true,
'hierarchical' => true,
'rewrite' => array('slug' => 'business-category'),
)
);
}
Right now my URLs are :
http://localhost/demo-project/directory/
http://localhost/demo-project/business-category/antiques/
http://localhost/demo-project/directory/a-lil-bit-of-sas/
It will be like below:
http://localhost/demo-project/directory/
http://localhost/demo-project/directory/category/antiques/
http://localhost/demo-project/directory/a-lil-bit-of-sas/
Just need to modify the above 2nd URL.
Can anyone please advise me?
Thanks,

Finally, I got the solution here:
add_action('init', 'cpt_resources');
function cpt_resources() {
$labels = array(
'name' => _x('Resources', 'snt'),
'singular_name' => _x('Resource', 'snt'),
'add_new' => _x('Add Resource', 'snt'),
'add_new_item' => __('Add Resource'),
'edit_item' => __('Edit Resource'),
'new_item' => __('New Resource'),
'view_item' => __('View Resource'),
'search_items' => __('Search Resources'),
'not_found' => __('Nothing found'),
'not_found_in_trash' => __('Nothing found in Trash'),
'parent_item_colon' => ''
);
$args = array(
'labels' => $labels,
'taxonomies' => array('resource_type'),
'public' => true,

'rewrite' => array( 'slug' => 'resources' ),
'capability_type' => 'post',
'hierarchical' => false,
'menu_position' => null,
'supports' => array('title','thumbnail', 'editor' ),
);
register_post_type( 'resources_post_type' , $args );
}
function resource_type() {
$labels = array(
'name' => _x( 'Resource Types', 'Taxonomy General Name', 'snt' ),
'singular_name' => _x( 'Resource Type', 'Taxonomy Singular Name', 'snt' ),
'menu_name' => __( 'Resource Types', 'snt' ),

'no_terms' => __( 'No items', 'snt' ),
'items_list' => __( 'Items list', 'snt' ),
'items_list_navigation' => __( 'Items list navigation', 'snt' ),
);
$args = array(
'labels' => $labels,
'hierarchical' => true,
'public' => true,
'show_ui' => true,
'show_admin_column' => true,
'show_in_nav_menus' => true,
'show_tagcloud' => true,
'rewrite' => array('slug' => 'resources/category')
);
register_taxonomy( 'resource_type', array( 'resources_post_type' ), $args );
}
add_action( 'init', 'resource_type', 0 );
function resources_cpt_generating_rule($wp_rewrite) {
$rules = array();
$terms = get_terms( array(
'taxonomy' => 'resource_type',
'hide_empty' => false,
) );
$post_type = 'resources_post_type';
foreach ($terms as $term) {
$rules['resources/category/' . $term->slug . '/([^/]*)$'] = 'index.php?post_type=' . $post_type. '&resources_post_type=$matches[1]&name=$matches[1]';
}
// merge with global rules
$wp_rewrite->rules = $rules + $wp_rewrite->rules;
}
add_filter('generate_rewrite_rules', 'resources_cpt_generating_rule');
Result :
