Keys in Mifare Desfire cards uing NXPLib

I'm trying to understand how can I manage keys for application with NXPLib. Example nr 10 helped a lot and now functionality for creating/writing all types of files is working. I can, of course, create an application but can't find some answers:

- How can I define how many keys are defined for the application? I see in the description that probably Keysettings2 is used for this but in the example, there is hardcoded value, and no explanation about bytes meaning. Is there any description of keySettings 1 and 2 ? Any enumes etc?


- I can't find a way how to grant different grants for different keys.
