Anyone know how to setup this starter with gatsby-plugin-feed properly?

[sparklesam]

This is still work in progress, as i experience difficulties hooking up the slicezone with the feed custom content part. Great if there are anyone to help!

{
      resolve: "gatsby-plugin-feed",
      options: {
        setup(ref) {
          const ret = ref.query.site.siteMetadata;
          ret.allPrismicPost = ref.query.allPrismicPost;
          ret.generator = "GatsbyJS Material Starter";
          return ret;
        },
        query: `
        {
          site {
            siteMetadata {
              author
              siteUrl
              title
              description
            }
          }
        }
      `,
        feeds: [
          {
            serialize(ctx) {
              const { rssMetadata } = ctx.query.site.siteMetadata;
              return ctx.query.allPrismicPost.edges.map(edge => ({
                date: edge.node.data.date,
                title: edge.node.data.title.text,
                description: edge.node.data.body[0].primary.text.text,
              }));
            },
            query: `
            {
              allPrismicPost(sort: { fields: [data___date], order: DESC }) {
                edges {

      },
    },```
