Watermark not being added to PDFs

[ga-it]

Describe the bug Good day. I have recently updated Collabora and Nextcloud, and noticed that no watermark is being added to pdfs. They are still added to word and excel documents.

To Reproduce Steps to reproduce the behavior:

1. Share a Nextcloud pdf to a group
2. View that shared pdf as that group member
3. No watermark

Expected behavior A watermark to appear on the document.
