📚 Is your documentation request related to a problem? Please describe. A clear and concise description of what the problem is. Ex. I feel I should be able to [...] but I can't see how to do it from the docs. i find out a little issue with vuex store. "userStore" interface is so diferent with vuex interface "userStore" which is

/// from vuex
useStore<S = any>(injectKey?: InjectionKey<Store<S>> | string): Store<S>;
/// from composition-api
useStore<S = any>(injectKey?: InjectionKey<S> | string): Store<S>;

So there will caught you have to import like

export const key: InjectionKey<State> = Symbol()
//instead of 
import {Store} from 'vuex'
export const key: InjectionKey<Store<State>> = Symbol()

what ever it a feature or a bug , you might need to update new document for this 🔍 Where should you find it? What page of the docs do you expect this information to be found on?

//https://composition-api.nuxtjs.org/packages/store/
import { defineComponent, useStore } from '@nuxtjs/composition-api'

export interface State {
  count: number
}

export const key: InjectionKey<Store<State>> = Symbol()

export default defineComponent({
  setup() {
    const store = useStore(key)
    const store = useStore<State>()
    // In both of these cases, store.state.count will be typed as a number
  },
})

@hotrungnhan Could you explain what you have tried and what isn't working for you? Ideally via a reproduction (https://template.nuxtjs.org).
