How to set a class to a link in breadcrumbs?

Question

WordPress

Let's say how you can add it to woocommerce Maybe you can somehow use the hook ?<a href="#" class="breadcrumb"></a>

add_filter( 'woocommerce_breadcrumb_defaults', 'jk_woocommerce_breadcrumbs' );
function jk_woocommerce_breadcrumbs() {
return array(
'delimiter' => ' / ',
'wrap_before' => '<nav class="woocommerce-breadcrumb" itemprop="breadcrumb">',
'wrap_after' => '</nav>',
'before' => '',
'after' => '',
'home' => _x( 'Аппартаменты', 'breadcrumb', 'woocommerce' ),
);
}
