import icon set (colibre)

How could I import an new icon set in LibreOffice. I tried via extension manager in the writer menu (menu Extra) - but it doesn’t work. If I copy the zip with the icons in the Folder where all the other icon sets are (LibreOffice - share - config) it does also not work.

Version 6.0.6.2 for Windows 10.

Hello, If you upgrage to v6.1.x the icon set is already present see → Icon Theme

Thanks
I had this version installed as well for a test - the icons were anyway blurry. Therefore I retreated back to the stable version for conservative users and tried to install the icon set as vector graphics - didn’t work.

I tried both versions of the 6.0.6.2 (architectures) - and also the newest version - all ended up in blurry icons you cannot keep. So I think I need another set of icons with better resolution - and for this the import would need to work…
