Share content from my private folder

Nextcloud version: 19.0.0
Operating system and version: Debian 10
Apache: 2.4.38
PHP version: 7.3

The shared link is generated, but when I try to access a not found file appears
As a user I should be able to share a file from my ‘private’ folder.

Steps to replicate it:

  1. Go to an external storage folder, with at least one image, and workflow group restriction
  2. Copy the federate link to share the image
  3. Open a private window
  4. Go to the link copied
