is there a way to achieve union queries with a defresolver? (not sure if I'm using the right terminology here) Similar to this example https://cljdoc.org/d/com.wsscode/pathom/2.3.0-alpha6/doc/pathom-developers-guide#_union_queries but using defresolvers basically I have a resolver that returns a list of things as a result, with different types, and I'd like the result not to return with pathom-not-found for the fields that aren't required for a given type
