The error message states: "Application: Not Satisfied." So perhaps your app does not fulfill the requirements. Now, I have only worked with app protection policys on iOS. This can only be done with apps built with the Intune SDK. There's a wrapper tool as well.
Here though is a very interesting link, that might bring you further (if I'm not completely wrong, which might be the case).
