Security Rule to Access an App without having access to the Stream
I'm trying to give permisson to user to specific apps without give them access to the stream where the apps are published. Why do I try such a "strange" thing? In this special case i'll created a mashup for those apps, therefore i only want to grant the user to the mashup and the should not be able to see the corresponding app in the hub (That's why I'm trying to hide the stream where the app is published)).
Therefore my question is it possible to give user directly access to an app without having access to the Stream? Or is there any other way how I can hide the stream to the user.
