How to show the icons of epub?

I installed the QuickLook plugins-epub.qlgenerator,it can extract the cover of epub as the icon in Finder.
But I find it don’t work when I opened devonthink views-as icons and as split.
Is it possible that the icon of epub in devonthink shows like it is in finder?

I know I can creat thumbnailss for files which can preview by spacebar now… :open_mouth:
Sorry for my mistake. :frowning:

Do you have DEVONthink > Preferences > Media set to create thumbnails? These will override the icons. Otherwise, DEVONthink will respect the icons set in Finder. Perhaps restarting DEVONthink would be helpful.
