Need help with displaying text field on woocommerce product category page

Hi there,

I am using the Metabox builder to create Metaboxes.

I would like to add a textarea field to the woocommerce product_category taxonomy. The theme that I'm using is Astra.

I have added this code to my functions.php file:

//custom Metabox test JP
add_filter( 'rwmb_meta_boxes', 'prefix_register_meta_boxes' );

function prefix_register_meta_boxes( $meta_boxes ) {
    $prefix = '';

$meta_boxes[] = [
    'title'      => esc_html__( 'Product categorie text', 'text-domain' ),
    'id'         => 'product-categorie-text',
    'fields'     => [
        [
            'id'   => $prefix . 'textarea_1jtphdq0vy',
            'type' => 'textarea',
            'name' => esc_html__( 'Textarea Field', 'text-domain' ),
        ],
    ],
    'taxonomies' => ['product_cat'],
];

return $meta_boxes;
}

//Function to dispay the field on the product-category page
add_action( 'woocommerce_after_shop_loop', 'product_category_intro', 13, 3 );
function product_category_intro() {
    $value = rwmb_meta( 'textarea_1jtphdq0vy' );
    echo $value;
}

The metabox is displaying correctly. But the field is not visible on the product category page. What am I doning wring here?

This is the product category page that I tested: https://bloemenbezorgenhaarlem.com/product-categorie/rozen/
