The documentation for Apollo Server mentions it can accept cors as an argument to the ApolloServer constructor: https://www.apollographql.com/docs/apollo-server/api/apollo-server.html

cors: <Object | boolean> (apollo-server)

Pass the integration-specific CORS options. false removes the CORS middleware and true uses the defaults. This option is only available to apollo-server. For other server integrations, place cors inside of applyMiddleware.

However, the type definition for Config does not include a cors object:

export interface Config extends Pick<GraphQLOptions<Context<any>>, 'formatError' | 'debug' | 'rootValue' | 'validationRules' | 'formatResponse' | 'fieldResolver' | 'cacheControl' | 'tracing' | 'dataSources' | 'cache'> {
    typeDefs?: DocumentNode | Array<DocumentNode>;
    resolvers?: IResolvers;
    schema?: GraphQLSchema;
    schemaDirectives?: Record<string, typeof SchemaDirectiveVisitor>;
    context?: Context<any> | ContextFunction<any>;
    introspection?: boolean;
    mocks?: boolean | IMocks;
    mockEntireSchema?: boolean;
    engine?: boolean | EngineReportingOptions;
    extensions?: Array<() => GraphQLExtension>;
    persistedQueries?: PersistedQueryOptions | false;
    subscriptions?: Partial<SubscriptionServerOptions> | string | false;
    uploads?: boolean | FileUploadOptions;
    playground?: PlaygroundConfig;
}

Running apollo-server-core v2.1.0.
