This application is quite different from regular lock-app. The app showcases the current implementation of the Door Lock cluster and doesn't rely on the On/Off cluster to do the job.
For now it is not possible to change lock parameters from the app, the functionality should be probably presented either as CLI or something that could be controlled from tests (like RPC in lighting-app).
The application could be build in the same manner as all-clusters-app:
