LGK Garage Door app issue

I installed the LGK Virtual Garage door app to close my garage door at set time and/or Mode change. I appear to be running into a minor problem, I’ve looked at the code and it appears that “Notifications” required is set to false however when I try to save it it tells me to fill out all required fields and the only way I can get this error to go away is by selecting a person to receive a push notification. I really don’t need a notification and was hoping this one would work, but does anyone have an idea as to why its requiring a push notification?

The App can be seen here https://github.com/SmartThingsCommunity/SmartThingsPublic/blob/746b9a6a38b69aa472296fc57fb6227b28c7c0bd/smartapps/lgkapps/lgk-virtual-garage-door.src/lgk-virtual-garage-door.groovy

I’m still new to all this but am I wrong in thinking if it says “required: false” that it should not be required? or is there something else in the app that I’m not seeing where it says it is?
