All we've seen from Clea's book is one panel of her with a drink; it might be just another crowd scene of magic people.
What we don't have is a confirmed speaking part in anything. Hopefully she gets a speaking part in Carol's book, but we don't know yet if that's even the real her. (Carol even says "Wanda, is that really you?" Though I guess it confirms she still remembers who Wanda is, that's something.)
