Access .riv file from Share Links

When sharing a project (via Share Links), I get access to an embed URL like this: https://rive.app/s/{ID}. But I'd like to access the path of the hosted .riv file instead. I can see (in the network panel of the embed site) that it's hosted on a public URL that includes both this ID, and my user ID, along with some third ID that I don't understand.

Is there way to get this URL (without first looking at the embed)?
