Enable CORS on API Gateway with Python CDK

Question

I have an API Gateway defined in the python cdk that will accept CURL Restful requests to upload / read / delete files from an S3 bucket:

api = api_gw.RestApi(self, "file-api",
                  rest_api_name="File REST Service")
        
        file = api.root.add_resource("{id}")
        
        get_files_integration = api_gw.LambdaIntegration(handler,
                request_templates={"application/json": '{ "statusCode": "200" }'})
        post_file_integration = api_gw.LambdaIntegration(handler)
        get_file_integration = api_gw.LambdaIntegration(handler)
        delete_file_integration = api_gw.LambdaIntegration(handler)
        
        api.root.add_method("GET", get_files_integration, authorization_type=api_gw.AuthorizationType.COGNITO, authorizer=auth)
        file.add_method("POST", post_file_integration);     # POST /{id}
        file.add_method("GET", get_file_integration);       # GET /{id}
        file.add_method("DELETE", delete_file_integration); # DELETE /{id}  

Is it possible to enable CORS on the API Gateway so that it will perform pre-flight checks and allow external access from a localhost on another machine?

I have attempted to use the existing add_core_preflight() method defined in the documentation I can find but believe this may no longer be valid as of CDK 2.0.
