When Referencing another Schema, how to Extract the URL from that Referenced Post?

    {
      name: "linkToNews",
      title: "Lien au publication de nouvelles",
      description:
        "Créer un lien vers un article de presse contenant plus d'informations sur les dates limites de soumission.",
      type: "reference",
      to: { type: "nouvelles" },
    },

*[_type == 'yourdoc']{ name, linkToNews-> }

*[_type == 'nouvelles']{
  name, 'slug': linkToNews->slug
}
