  MyVendor\MyExtension\Backend\EventListener\MyEventListener:
    tags:
      - name: event.listener
        identifier: 'my-extension/backend/link-handlers'

Read how to configure dependency injection in extensions.

The corresponding event listener class:

<?php

declare(strict_types=1);

namespace MyVendor\MyExtension\Backend\EventListener;

use TYPO3\CMS\Backend\Controller\Event\ModifyLinkHandlersEvent;

final class MyEventListener
{
    public function __invoke(ModifyLinkHandlersEvent $event): void
    {
        $handler = $event->getLinkHandler('url.');
        $handler['label'] = 'My custom label';
        $event->setLinkHandler('url.', $handler);
    }
}
