Hi there – I'm having trouble getting the preview toolbar to work on my repository. I am using "@nuxtjs/prismic": "^1.2.4" and have followed the setup guide here: https://prismic.io/docs/vuejs/beyond-the-api/previews-and-the-prismic-toolbar
I'm sure I had the little edit pencil icon on my site last week, but now I can't get previews to work at all. Does it need to be activated?
