From be3ae8a6600191ec88a65056df7aec848a662b58 Mon Sep 17 00:00:00 2001
From: Ferdinand Thiessen <opensource@fthiessen.de>
Date: Wed, 4 Sep 2024 16:57:14 +0200
Subject: [PATCH] fix: Make the default uploader global

This way it is possible e.g. for `files_sharing` and `files` to share the same uploader instance.
