auth to the context object. This works great for most requests I've made, but I'm having trouble now that I'm trying to use getStaticProps and createServerSideHelpers.AuthContext type so that auth can be undefined, which would make sense when the page is generated at build. But is there a way to get auth info in there, when the page gets regenerated later as a user visits? Or would I need to make any auth-related stuff part of the client code?
