Sharing an Appian Community Edition App with potential customers?

Up to now, all my Appian implementations were developed and running on-premise. Just now I built a quick demo app using the Appian Community Edition.

1. I would like to demonstrate to a potential client, how the "Appian code" looks, meaning they want to see the ZIP-files created when downloading a package, since they intend to use SonarQube.
   Somehow, downloading a package or the whole App does not seem to be possible for me. Which user rights do I need to have to be able to show this?
2. Similar issue concerning show-casing on-the-fly-built Appian demo apps to customers: I would like to share a (temporary) URI with the client, so that (s)he can try out the Appian App on her/his phone, e.g. https://us.appian.community/suite/sites/myApp - but the later requires that (s)he creates an account with Appian first which takes too much time for decision makers. I just want to show-case that the App I just built indeed looks good on any device.

Any help is appreciated.
