You can use plugin for that instead of event and apply your code logic for redirection :

app/code/RH/CustomPlugin/etc/frontend/di.xml

<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/ObjectManager/etc/config.xsd">
    <type name="Magento\Wishlist\Controller\Index\Plugin">
        <plugin name="guest_wishlist_plugin" type="RH\CustomPlugin\Plugin\GuestPlugin" sortOrder="10"/>
    </type>
</config>

app/code/RH/CustomPlugin/Plugin/GuestPlugin.php

<?php

namespace RH\CustomPlugin\Plugin;

class GuestPlugin {

    public function beforeBeforeDispatch(\Magento\Wishlist\Controller\Index\Plugin $coreSubject, $subject, $request) {
        $writer = new \Zend\Log\Writer\Stream(BP . '/var/log/Rohan.log');
        $logger = new \Zend\Log\Logger();
        $logger->addWriter($writer);
        $logger->info('Your text message');
        //Apply your code logic
        return [$subject, $request];
    }

}
