Gatsby sitemap generator isn't filterting the pages

Question

I'm trying to generate sitemaps via gatsby-plugin-sitemap and it works with all the default options and generate the sitemaps however if I try to modify the sitemap generation in anyway it doesn't seems to have any affect whatsoever e.g. I want to remove the changefreq and priority, it doesn't work and when I try to filter the pages it doesn't work either.

This is how my config looks like:

{
            resolve: `gatsby-plugin-sitemap`,
            options: {
                output: `/testsitemap.xml`,
            },
            query: `{
                        site {
                            siteMetadata {
                                siteUrl
                            }
                        }
                        allJsonJson {
                            edges {
                                node {
                                    noindex
                                    hrefs {
                                        href
                                    }
                                }
                            }
                        }`,
            serialize: ({ site, allJsonJson }) => {
                return allJsonJson.edges
                    .filter(({node}) => (
                        node.noindex !== true
                    ))
                    .map(({node}) => {
                        node.hrefs.map(({href}) => {
                            return {
                               url: `${site.siteMetadata.siteUrl}${href}`
                            };
                        })
                     })
            },
        }

This is driving me nuts as I'm trying to make it work for quite sometime now and can't proceed at all. Any ideas?

GraphQL Editor:

"allJsonJson": {
      "edges": [
        {
          "node": {
            "noindex": null,
            "hrefs": [
              {
                "href": "/about/"
              },
              {
                "href": "/aa/test.../"
              }
            ]
          }
        }
     ]
   }

I nearly moved to Next.js trying to figure this out...

 {
      resolve: 'gatsby-plugin-sitemap',
      options: {
        query: `
          {
            allSitePage {
              nodes {
                path
                pageContext
              }
            }
          }
        `,
        resolveSiteUrl: () => 'https://yourwebsite.com/',
        resolvePages: ({ allSitePage: { nodes: allPages } }) => {
          return allPages.filter((page) => {
            // Don't want to add private routes to the sitemap
            if (page.path.includes('/dashboard')) {
              return false;
            }

            return true;
          });
        },
      },
    },

It seems like the plugin doesn't support anything other than allSitePage as mentioned in this ticket.
