Help sorting files in the panel using a custom method

I’m trying to sort files in a section by upload date so that their order doesn’t change when the metadata changes.

Here’s what I’m trying to do:

<?php
Kirby::plugin('test/file-methods', [
    'fileMethods' => [
        'modifiedDate' => function($format = null) {
            return Str::date(F::modified($this->root()), $format);
        },
    ],
    'filesMethods' => [
        'sortByUploadedDate' => function($direction = 'asc') {
            return $this->sortBy(fn ($file) => $file->modifiedDate(), $direction);
        }
    ]
]);

Blueprint file:

sections:
    files:
        headline: Files
        type: files
        layout: cards
        size: medium
        limit: 100
        sortBy: sortByUploadedDate desc
        info: "<small>Upload {{ file.modifiedDate('d.m.Y H:i') }}</small><br><small>Modified {{ file.modified('d.m.Y H:i') }}</small><br>{{ file.niceSize }}"

But the files in the panel aren’t sorted by upload date. I’m asking for help from the community. Thanks in advance!
