I want to create a Garmin watchface app with the settings, but I do not want to publish it to Garmin Store. I just want to use it for myself. I want to have some settings in this app. As I understand, I cannot change settings via mobile app for this app because it is not published. I read somewhere that theoretically it is possible to create settings file manually and put it here \GARMIN\APPS\SETTINGS and it will work.
Can someone help me to create such a file? What is the format? Is it possible at all?
