I'm unsure how I to store current user inside and later access to it in my resolvers. What is the recommended way to do this?

I see there are some variables set like so:

    var globalVariables = <String, dynamic>{
      '__requestctx': req,
      '__responsectx': res,
    };

But not sure how to add data to them.
