Creating custom URL in Kirby

Hi, I’m trying to change the url from produkt.soap.php to soap.php. I read this Routing | Kirby CMS (getkirby.com) and applied the code as follows with no sucess:

return [
  'routes' => [
    [
      'pattern' => '/url',
      'action'  => function () {
        // do something here
        // when the URL matches the pattern above
      }
    ],
    [
      'pattern' => '/url',
      'action'  => function () {
        // ...
      }
    ]
  ]
];

This is not a url, but a template name. Please indicate the page routes you want to change

Here is how page urls are created from the content folder structure: Overview | Kirby CMS
