looking good! left some comments, but I haven't tested yet (waiting for instructions for fidesplus setup!)

@allisonking I think I've addressed everything from the first round of feedback 👍

tested it out and it works great! 😎 would also be nice to have cypress tests for this, though it could wait until things are more stable if you'd prefer!
