/**
 * The GraphQlAPI class extends the RestAPI class and manages the requests to a GraphQL API.
 *
 * - The base URL of the API is automatically concatenated to the path of the requests.
 * - The config of the API is automatically merged with the config of the requests.
 * - The status of the requests is automatically tracked and can be accessed through the status property.
 * - The requests are sent with the Fetch class, so all features of the Fetch class are available.
