How to use the @kubernetes/client-node.Log function in @kubernetes/client-node

function followK8sLog(container: K8sContainer): request.Request {
    const k8sLog = new k8s.Log(container.config);
    const logStream = new Writable({
        write: (chunk, encoding, callback) => {
            container.log.write(chunk.toString());
            callback();
        },
    });
    const doneCallback = e => {
        if (e) {
            if (e.message) {
                container.log.write(e.message);
            } else {
                container.log.write(stringify(e));
            }
        }
    };
    const logOptions: k8s.LogOptions = { follow: true };
