How push route params from main-app to sub-app?

I have two nuxt applications: `main-app` and `sub-app`.
`main-app: localhost:3000`
`sub-app: localhost:3001`

In my sub-app I have one route `/pages/item/_id.vue` that was mapped in main-app.
E.g from main-app: `localhost:3000/item/1`

When I make this: `this.$router.push({ name: 'item', params: { id: 1 } })` from main-app the sub-app get `id` as `undefined`.

Can I use `router.push` or I only have that use vuex to the shared resources between main and sub apps?
