I Installed both Libreoffice and Zotero via Flatpak. I then installed the Zotero plugin for Libreoffice. All good so far.
However, Libreoffice cannot access Zotero. Means, I get the Zotero panel in Libreoffice, but it cannot access the Zotero cataloque. Means, the communication between Libreoffice and Zotero is somehow broken.
Any idea how to make both working together?
