Electron/Angular redirect without localhost?

I followed some examples here to make my Electron/Angular desktop app work with Okta, but I’m getting pushback from my IT dept about setting the redirect_uri back to http://localhost:8000. I guess they have a “rule” about not using localhost in the production Okta instance.

The IT guy sent me a link that showed IOS apps using a pattern of myapp://callback. Is there something similar that would work with Electron?
