Recover files not created on Linux

After Power went out from my Laptop all open unsaved documents were lost. The recover folder in /home/{user}/.local/share/onlyoffice/desktopeditors/ does not even exist (actually /home/{user}/.local/share/onlyoffice/desktopeditors/ is completely empty).
OS version: Linux Mint 22.3 - Cinnamon 6.6.7 Desktop 64-bit with a 6.17.0-29 Kernel
App version: 9.3.1.8
Downloaded from: ONLYOFFICE website

Hello @Frodo
Sorry for the late reply. Could you also check the “Recover Files” tab in the app itself and confirm whether it is empty?
Also, is it possible to update the app to v.9.4?
