To give permission for your high-level app to talk to your real-time app, and vice versa, the "AllowedApplicationConnections" field of the app_manifest.json for each app must contain the component ID of the other app. See here for details. The "ComponentId" is itself a field in the app manfiest: your new app(s) likely have different IDs to the sample apps.

Also, if you are deploying through Visual Studio (Code), you need to declare each app as a 'partner' of the other so one is not deleted when the other is deployed. See here for details of that. The RT app error that you see may come from it being deleted when the high-level app is deployed.
