How to use zeroValue function to initialize the default value?

[amanshu-kataria]

I used iron-localstorage earlier, but since it has been deprecated I thought of using app-localstorage-document. I want to initialize the default value when the key is first created. In iron-localstorage I used on-iron-localstorage-load-empty event to initialize the default value. But nothing similar thing is available here.
