Transférer une page ou un modèle Bricks entre sites

Cette requête exporte une page ou un modèle Bricks depuis ce site WordPress vers un site WordPress downstream.

Le plugin Gato GraphQL (version gratuite) doit être installé sur le site downstream. Il doit exposer un endpoint avec les "Nested mutations" activées.

Les deux sites doivent autoriser l'accès au type de post personnalisé correspondant, bricks_template et/ou page.

Le paramètre $update indique s'il faut créer ou mettre à jour une page/un modèle dans le site downstream.

Si la page/le modèle est mis à jour, l'identifiant commun entre les sites upstream et downstream est le slug.
