Hello. i want to remove order id section from the tracking page. I already got the code. but didnt understand which part should i edit. can you help me with it?

Code:

<?php
// Don’t call the file directly
if ( !defined( ‘ABSPATH’ ) ) exit;

if(!class_exists(‘CBWCT_ORDER_TRACKER’)) {
return;
}

// set variable for getting value from input field
$get_order_number = sanitize_text_field($_POST[‘order_number’]);
$get_phone_number = sanitize_text_field($_POST[‘phone_number’]);

if(empty($get_order_number) || empty($get_phone_number)) { // search field empty check
apply_filters( ‘cbwct_order_number_phone_number_required’, esc_html__(‘Order Number & Phone field is required’, ‘cbwct’ ));
}else {

if(!isset($get_order_number)) { //order number empty
    $order = NULL;

}else {
    if(CBWCT_ORDER_TRACKER::order_number_exists($get_order_number) == false) {
         echo apply_filters( 'cbwct_order_is_not_found', esc_html__('order is not found!', 'cbwct') , $get_order_number );
    }else {
        $order = wc_get_order( $get_order_number ); // set order number

        $order_data = $order->get_data(); // The Order data

        // get user phone number from shipping form
        $user_shipping_phone_number = isset($order_data['shipping']['phone']) ? $order_data['shipping']['phone'] : '' ;

        // get user phone number from billing form
        $user_billing_phone_number = isset($order_data['billing']['phone']) ? $order_data['billing']['phone'] : ''; 

        // set phone number value
        if(!empty($user_billing_phone_number)) {
            $user_phone = $user_billing_phone_number;
        }elseif($user_billing_phone_number) {
            $user_phone = $user_billing_phone_number;
        }else {
            $user_phone = '4654654';
        }

        if($get_phone_number === $user_phone || $get_phone_number === $user_phone) {                            
                if(!empty($order)) {
                    $order_data = $order->get_data(); // The Order data

                    require_once( CBWCT_TRACKER_PATH . '/inc/templates/progressbar.php'); 
                    require_once( CBWCT_TRACKER_PATH . '/inc/templates/result.php'); 
                }
        }else {
            echo apply_filters( 'cbwct_order_is_not_found', esc_html__('order is not found!', 'cbwct'), $get_order_number );
        }
    }
}
