Custom Breadcrumbs in SEO Title

Hello! I’m trying to print the breadcrumbs for WooCommerce product category pages in the SEO title and meta description through Yoast. I’ve looked at the variable page (https://yoast.com/help/list-available-snippet-variables-yoast-seo/), but have not been able to get something working that does what I need.

Would there be a way to print breadcrumbs as a custom Yoast variable? Here is what I have…please advise. Thanks so much!

add_filter( 'woocommerce_breadcrumb_defaults', 'diy_woocommerce_breadcrumbs' );
function diy_woocommerce_breadcrumbs() {
    return array(
            'delimiter'   => ' ',
            'wrap_before' => '',
            'wrap_after'  => '',
            'before'      => '',
            'after'       => '',
        );
}

add_filter( 'woocommerce_breadcrumb_defaults',function( $defaults ) {
    unset($defaults['home']);//removes home link.
    return $defaults;//returns rest of links
});

remove_action( 'woocommerce_before_main_content', 'woocommerce_breadcrumb' );

function get_diy_catlist() {
    return woocommerce_breadcrumb();
}

// define the action for register yoast_variable replacments
function register_custom_diyyoast_variables() {
    wpseo_register_var_replacement( '%%diycatlist%%', 'get_diy_catlist', 'advanced', 'some help text' );
}

// Add action
add_action('wpseo_register_extra_replacements', 'register_custom_diyyoast_variables');
