Webdavs from LibreOffice - shared link

http://www.techrepublic.com/article/how-to-save-libreoffice-documents-to-your-nextcloud-server/ shows how to use NextCloud with LibreOffice over Webdav.

But it does not show how to use a share-link as webdav.

How can I use a share link that allows upload like this in LibreOffice?
