No, it's Web Assembly (compiled by Emscripten) so I can provide a URL but not a file (unless the file is just a dummy redirect of course) I can't see anywhere that I can specify a URL so that it is listed with the downloads as an alternative way of running it.
Ooh, right, 'cause it's hosted on your site. Yeah, in that case you have to upload an index.html that does nothing except load that URL in an iframe. It's fairly common.
