Accessing the prototype in the vuex_a getter, how?

Question

Vue.js

I connected the vue2-storage package to the Quasar Framework, because of the convenient work with ttl.

Vue.use...
Vue.prototype.$Ls = Vue.$storage

I use it in one of the vuex modules. In the actions of this module, I see it as this._vm.$Ls.get('key')
and in the getter of this module, would I get access to it?
