Ring Retrofit Driver Changes

I have just installed 2 Ring Retrofit kits into my Ring system and would like to expose the contacts to Hubitat. I have installed the Unofficial Ring App using HPM and created the Retrofit Alarms devices. I would like to create child devices for each of the contacts on the Retrofit devices so that I can automate actions for the on and off conditions of those contacts. I have not previously made changes to driver codes and would appreciate any assistance in how to make that happen

Thank you in advance for your suggestions and examples
