how to make shield work for conditionally lazyLoaded schema

[ethdev279]

I'm trying to use graphql shield with envelop's useLazyLoadedSchema to use public and private schema's conditionally based on authorization passed to context like below

const permissions = shield({
Query : {
...
...
...
},
Mutation:{
...
...
...
}
});

const server = createServer({
  plugins: [
    useGraphQLMiddleware([permissions]),
    useLazyLoadedSchema(({ request }) => (request.headers.get('authorization') ? privateSchema : publicSchema))
  ]
})

So when we do this, shield may not be able to apply all rules to conditionally loaded schema so it throws the following expected error

It seems like you have applied rules to Query.getCompanies, Query.getReports fields but Shield cannot find them in your schema

is there any way we can suppress this error or make shield aware of the rules applied to non existing schema. instead of throwing error it should ignore it.
