@robert good question. following for the answer :)
I haven't found a good answer yet.
@robert The package is called dolphin-nextcloud in Debian.
@robert Of course :-) There is a nice Dolphin integration for the sync client and you can sync nicely your calendars and contacts with KDE Kontact.
@bjoern Do you know what it is called?
@robert Do you mean the Dolphin integration. This depends on your distribution, if you have packages with the Nextcloud sync client you should also have a package that provides the Dolphin integration, on Debian it is calles "dolphin-nextcloud" for example. For Kontact see https://docs.nextcloud.com/server/15/user_manual/pim/sync_kde.html (the configuration is not as easy/automated as with GNOME Online Accounts but once configured it works great)
@robert I forget how _exactly_ it works but it's like an integration into Dolphin.
