Hugo Page Resources - can't get a match

I want to write a generic shortcode for my hugo-powered webseite that adds a download section to my pages listing all the files in the downloads folder.

I have the website layed out like this:

.
├── content
│   └── press
│       ├── downloads
│       │   ├── presstext.pdf
│       │   └── presskit.zip
│       ├── _index.de.md
│       └── _index.en.md
└── layouts
    └── shortcodes
        └── downloads.html

My markdown file looks like this:

---
title: "Downloads"
date: 2019-10-26T09:59:26+01:00
draft: true

resources:
- src: downloads/presskit.zip
  title: Presskit
  params:
    icon: pdf
- src: downloads/presstext.pdf
  title: Presstext
  params:
    icon: pdf
---

Look at my awesome downloads:
{{< downloads >}}

And my shortcode looks like this:

<ul class="downloads">
    {{ range .Page.Resources.Match "downloads/*" }}
    <li>
        <a target="_blank" href="{{ .Permalink }}">
            <i class="far fa-file-{{ .Params.icon }}"></i> {{ .Title }}
        </a>
    </li>
    {{ end }}
</ul>

But no document ever get's matched, so {{ range .Resources.Match "downloads/*" }} always returns empty. Am I overlooking something?

I already tried:

{{ range .Resources.Match "downloads/*" }}
{{ range .Resources.Match "/downloads/*" }}
{{ range .Resources.Match "**.zip" }}
{{ range .Resources.Match "**.pdf" }}
{{ range .Resources.Match "press/downloads/*" }}
{{ range .Resources.Match "/press/downloads/*" }}
