Invalidate context

Hey guys ! 👋 I think i'm missing something on how to properly invalidate the root context. I created a router with a context like this : 
const router = createRouter({
  routeTree,
  context: {
    session: async () => {
      const session = await authClient.getSession();
      return session;
    },
    queryClient,
    establishmentId: document.cookie
      .split("; ")
      .find((row) => row.startsWith("establishment_id="))
        ?.split("=")[1] ?? null
  },
  defaultPreload: "intent",
  scrollRestoration: true,
  defaultStructuralSharing: true,
  defaultPreloadStaleTime: 0,
});
const router = createRouter({
  routeTree,
  context: {
    session: async () => {
      const session = await authClient.getSession();
      return session;
    },
    queryClient,
    establishmentId: document.cookie
      .split("; ")
      .find((row) => row.startsWith("establishment_id="))
        ?.split("=")[1] ?? null
  },
  defaultPreload: "intent",
  scrollRestoration: true,
  defaultStructuralSharing: true,
  defaultPreloadStaleTime: 0,
});
So every time i use useRouter().invalidate() i'm expecting the value of establishmentId to be recomputed ? It doesn't seem to be the case because even if i update the cookie, the value does not change. I tried to log the value of establishmentId by using a self called function and it seems to be only called once Am i missing something about context (or maybe it's the cookie usage)

you would need to put this into e.g. root's beforeLoad and return it from there the context you pass into createRouter is static
