The following code send a message to new members of my buddypress site upon registration. How is it possible to adapt this so that when a customer leaves a note at the checkout, it gets sent to my ‘messages’ inbox?

function send_woo_note_to_messages( $user_id) {

if ( ! bp_is_active( 'messages' ) )
    return;
     
$user_info = $user_id ? new WP_User( $user_id ) : wp_get_current_user();

$args = array(
    'sender_id' => 1, // This will be the customer id.
    'thread_id' => false,
    'recipients' => $user_id, // This will be the admin id (1)
    'subject' => 'Customer Note',
    'content' => sprintf( __( 'Insert customer note here' ),
    'date_sent' => bp_core_current_time()
);

$result = messages_new_message( $args );
}

add_action( 'bp_core_activated_user', 'send_woo_note_to_messages', 2 );

bp_core_activated_user is used to send the message upon account activation. I figured that I could use woocommerce_new_order_note_data to aid my request, but apparently not.
