Webp in Thumbnail Mode

Greetings Gurus, is there a native or third party way to give opus the ability to display webp images?

A WebP plugin has been included since 12.7.2 / Feb 2018:

WebP images can now be displayed in the viewer, preview pane, thumbnails. The image converter can convert from WebP to other formats (but not the other way around). Alpha channel transparency is supported. Metadata, tiled images (over 16kx16k) and animated images are not currently supported.

Thanks Leo.
