Getting app settings in mobile app

Options

I am able to declare app specific settings in app.properties file of my mobile bundle. For example:

restUrl.type=string
restUrl.displayName=REST Server URL
restUrl.descriptions=If REST server is not proxied via Appworks Gateway then provide full URL starting with http(s)://, otherwise provide relative URL starting with slash.
restUrl.default=/api
restUrl.seqNo=1
restUrl.readOnly=false

I can edit the value using settings icon in the Gateway UI (against the app). Question is - how can we access this settings value from mobile app code? There is no API to access settings in appworks.js.
