   • BUse a policy template to call the Azure Function after the API response and replace the body.
   • CAdd the Azure Function as an additional operation in the OpenAPI definition and call it from the connector.
   • DCreate a custom connector action that calls the Azure Function, which in turn calls the external API and returns JSON.
