Where can i find the config files of the sidebar from dolphin (file manager), where my Bookmarks for folders and devices are saved.

I want to edit them manually, backup them and export the file to a second user profile on my debian gnu/linux.

I found only the ~/.config/dolphinrc for some global settings but not my bookmarks.

The ~/.local/share/kxmlgui5/dolphin is empty and in ~/.local/share/dolphin/view_properties i found nothing.
