How to add the "New..." context menu in Dolphin KDE

[Usserr]

Hello,

I’ve got OpenSuSE Leap 42.3 with the latest versions of KDE and Dolphin, I guess (I’m not sure how to check the Desktop environment or any other app’s installed version indeed) and LibreOffice 6.0.3.2-18.1.x86_64. When in the browser though, I’ve got nothing related to LibreOffice in the Create New contextual menu. How do I add “LibreOffice Writer Document,” “Spreadsheet” etc.?

On the following page someone suggest going to the “Services” category in Dolphin’s preferences, but LibreOffice is not in the options there there. Maybe a plugin needs to be installed here too - does anyone know how it’s called?

Thanks in advance!

Do these Q&As at either Unix.Stackexchange or Superuser.com help? This is more of an operating system question than a LibreOffice question.
