Filetype support (clicking an svg starts collabora but fails to open)

When clicking an SVG file I get this message:

Failed to load the document. Please ensure the file type is supported and not corrupted, and try again.

When I check I see a huge bunch of ext, file and mime types. I suppose that is supported file types?

As svg is among them why doesn’t it open svg? If it is not supported, where do I control on what filetype collabora is triggered from within NC?
