I build a custom plugin which works with WooCommerce, which allow users to hide or show any billing or shipping fields on checkout page as per their need. Now, Woo Commerce introduced a new widget named "checkout" as Gutenberg block. Custom plugin working fine to hide or show any billing or shipping fields on classic checkout, but it is not working with latest checkout widget. How I can customize the checkout widget, so I can show or hide fields in it by using my custom plugin. Is there any suitable hooks and filters available that I can use to achieve this?
