Programatically update cart subtotal and order total

Hi,

I have updated PRODUCT subtotals using this filter:

add_filter( 'woocommerce_cart_item_subtotal', 'change_product_subtotal_on_condition', 10, 3 );
function change_product_subtotal_on_condition( $subtotal, $cart_item, $cart_item_key ) {
    $newsubtotal = wc_price( $cart_item['data']->get_price() * ($cart_item['quantity'] - 1 );
    $subtotal = sprintf( '<s>%s</s> %s', $subtotal, $newsubtotal );

    return $subtotal;
}

It works fine, however CART subtotal and order total are not updated. Could you please advise me how to update both of them?

I tried

add_filter( 'woocommerce_cart_subtotal', 'update_cart_subtotal', 10, 3 );
function update_cart_subtotal( $cart_subtotal, $compound, $obj ) {
    $new_cart_subtotal = wc_price( WC()->cart->subtotal);
    $cart_subtotal = sprintf( '<del>%s</del> <b>%s</b>', $cart_subtotal , $new_cart_subtotal );

    return $cart_subtotal;
}

This does not update CART subtotal with newly calculated PRODUCT subtotals in my first filter.
