Track Woocommerce Orders only with phone numbers

I am using this woocommerce default code for tracking where customer have to enter both order id and phone number to track the order.

and here is the code for this

// Create a custom tracking shortcode
add_shortcode( 'dvs_order_tracking', 'dvs_tracking_request' );
function dvs_tracking_request() {
    if ( is_null( WC()->cart ) ) {
        return;
    }
    $nonce_value = wc_get_var( $_REQUEST['woocommerce-order-tracking-nonce'], wc_get_var( $_REQUEST['_wpnonce'], '' ) );

    if ( isset( $_REQUEST['orderid'] ) && wp_verify_nonce( $nonce_value, 'woocommerce-order_tracking' ) ) { 
        $order_id    = empty( $_REQUEST['orderid'] ) ? 0 : ltrim( wc_clean( wp_unslash( $_REQUEST['orderid'] ) ), '#' );
        $order_email = empty( $_REQUEST['order_email'] ) ? '' : sanitize_text_field( wp_unslash( $_REQUEST['order_email'] ) );
        $order_phone = empty( $_REQUEST['order_phone'] ) ? '' : sanitize_text_field( wp_unslash( $_REQUEST['order_phone'] ) );   
        $dvs_tracking_phone = get_option( 'dvs_tracking_phone' );

        if ( current_user_can( 'manage_options' ) ) {
            if ( ! $order_id ) {
            wc_print_notice( __( 'Order number is required', 'woocommerce' ), 'error' );
            }
            else {
                $order = wc_get_order( apply_filters( 'woocommerce_shortcode_order_tracking_order_id', $order_id ) );
                if ( $order && $order->get_id() ) {
                    do_action( 'woocommerce_track_order', $order->get_id() );
                    wc_get_template(
                        'order/tracking.php',
                        array(
                            'order' => $order,
                        )
                    );
                    return;
                } else {
                    wc_print_notice( __( 'Sorry, order could not be found.', 'woocommerce' ), 'error' );
                }
            }
        }
        else if($dvs_tracking_phone == 1) {
            if ( ! $order_id ) {
                wc_print_notice( __( 'Order number is required', 'woocommerce' ), 'error' );
            } elseif ( ! $order_phone ) {
                wc_print_notice( __( 'Mobile Number is required', 'woocommerce' ), 'error' );
            } else {
                $order = wc_get_order( apply_filters( 'woocommerce_shortcode_order_tracking_order_id', $order_id ) );

                }
                if ( $order && $order->get_id() && strtolower( $order->get_billing_phone() ) === strtolower( $order_phone ) ) {

                }
            }
        }
        else {
            if ( ! $order_id ) {
                wc_print_notice( __( 'Order number is required', 'woocommerce' ), 'error' );
            } elseif ( ! $order_email ) {
                wc_print_notice( __( 'Email Address is required', 'woocommerce' ), 'error' );
            } else {
                $order = wc_get_order( apply_filters( 'woocommerce_shortcode_order_tracking_order_id', $order_id ) );
                if ($order_email == '1122') {
                    do_action( 'woocommerce_track_order', $order->get_id() );
                    wc_get_template(

                    );
                    return;
                } else {

                }
            }            
        }
    }
    wc_get_template( 'order/form-tracking.php' );

?>

<?php } 

I wanted to give an option to my customers that they can either put their order number or phone number and their order tracking page will pop up.

Note: All my orders have phone numbers so there will be no issue with an empty phone number field.
