Also verifying in the settings that the HPB and turn server work. - [ ] Imaginary by having a look if when uploading a new picture in Nextcloud, it adds some log entries to the container - [ ] Fulltextsearch by trying to search for a heading inside a file in Nextcloud - [ ] When Collabora is enabled, it should show below the Optional Addons section a section where you can change the dictionaries for collabora. `de_DE en_GB en_US es_ES fr_FR it nl pt_BR pt_PT ru` should be a valid setting.
