How can I use Chromecast code with Cheapcast?

I'm trying to understand how I can use ChromeCast in my app using this
code: https://github.com/googlecast/cast-ios-demo-player. But I don't have
yet ChromeCast and I have to test how the code working with Cheapcast. I
found here: https://github.com/mauimauer/cheapcast/issues/6 some
istructions, but I don't understand. To operate the demo code, I have need
to replace @"[YOUR_APP_NAME]" with an hex app identifier (from Google
whitelist email). But I don't have ChromeCast so I don't have this
identifier. How can I do? Using Cheapcast what can I put into
@"[YOUR_APP_NAME]" place? Thank you very much.
