vuex-easy-firestore: Request: modifiedHook to be triggered on local change

Heya! So, I’m at a point where one vuex module needs to know when an item has changed on the server and then ask another vuex module to do some work. I am trying to use the modifiedHook but it doesn’t seem to fire or register a “modified” trigger for me. My current, hacky workaround:

  serverChange: {
    convertTimestamps: {
      created_at: '%convertTimestamp%',
      updated_at: '%convertTimestamp%'
    }
  },
  sync: {
    patchHook: async function (updateStore, doc, store) {
      await updateStore(doc)
      // I don't like this! Using because the modifiedHook for serverChanges doesn't seem
      // to be working...
      setTimeout(async () => {
        await store.dispatch('profilesData/refreshProfiles', null, { root: true })  
      }, 1000)
    }
  },

But I know this is either a misunderstanding on my part or maybe a bug? The module I want to listen to (users) is a ‘collection’ - I’ve tried adding a modifiedHook like so:

export default {
  firestorePath: 'users',
  firestoreRefType: 'collection',
  moduleName: 'profilesData',
  statePropName: 'profiles',
  namespaced: true,
  serverChange: {
    convertTimestamps: {
      created_at: '%convertTimestamp%',
      updated_at: '%convertTimestamp%'
    },
    modifiedHook: async function (updateStore, doc, id, store) {
      console.log('I am in here') // <--- this never gets called when an item in the users collection is patched.
      await updateStore(doc)
    }
  },
  state,
  getters,
  actions,
  mutations
}

And in the other module (at path users/{userId}) which is a ‘doc’ type, I try making the patch that I thought should trigger the server change in users collection:

async updateUser ({ dispatch }, userData) {
    try {
      await dispatch('patch', userData) // <--- this would have done a PATCH to a resource in the users collection
    } catch (error) {
      console.log(error)
    }
  },

I have verified in Firestore that the data is getting changed as I would expect - just the modifiedHook never prints that console.log.
