Create House Number Field

Hello, many customers forget to put both their street name and house number in one field. its so awful to have to contact them all the time, plus, at times our emails just lands in the spam and customer waits ages and only comes to us angry. i have a code which doesnt work on Woocommerce Blocks, goal is to add a house number field on woocommerce blocks and make both street and number required. i have this code for a start but it doesnt function on wblocks. Please help us with our burden.

add_filter( ‘woocommerce_default_address_fields’, ‘custom_override_default_checkout_fields’, 10, 1 );
function custom_override_default_checkout_fields( $address_fields ) {
$address_fields[‘address_2’][‘placeholder’] = __( ‘dssfsd’, ‘woocommerce’ );

return $address_fields;
}
