'label' => __( 'Delivery Instructions', 'text-domain' ),
'placeholder' => __( 'Enter any special delivery instructions here', 'text-domain' ),
'required' => false,

Code Explanation
- In this code snippet, we’re using the woocommerce_billing_fields filter hook to add a custom field labeled “Delivery Instructions” to the billing address section. This field allows customers to provide any special delivery instructions for their orders.
- The field is optional (not required), has a placeholder text for guidance, and is of type “text.”
