How do I set Nextcloud Folder Icon?

Hi, I have a Nextcloud folder, but there's no icon on it, just plain folder. How do I set the Kora Nextcloud icon? Thank you.

EDIT: I forgot to mention my DE: Xfce

I'm pretty sure that depends on your file manager, not DE. In Dolphin there's a UI to do that. It creates a .directory file inside the folder with the contents like

[Desktop Entry]
Icon=folder-onedrive

I just tested with Thunar and it doesn't apply that icon and I think that it doesn't support custom folder icons.

Thanks for your reply. In fact, it's very much indeed so. Here's the last nail in the coffin.
