How to use the @azure/ms-rest-nodeauth.DeviceTokenCredentials function in @azure/ms-rest-nodeauth

let auth = (await globalConfig.get(AUTH)) as AuthResponse | null;

  // if old AUTH config is not found, we trigger a new login flow
  if (auth === null) {
    auth = await retryLogin(auth);
  } else {
    const creds = auth.credentials as DeviceTokenCredentials;
    const { clientId, domain, username, tokenAudience, environment } = creds;

    // if old AUTH config was found, we extract and check if the required fields are valid
    if (creds && clientId && domain && username && tokenAudience && environment) {
      const cache = new MemoryCache();
      cache.add(creds.tokenCache._entries, () => {});

      // we need to regenerate a proper object from the saved credentials
      auth.credentials = new DeviceTokenCredentials(
        clientId,
        domain,
        username,
        tokenAudience,
        new Environment(environment),
        cache
      );

      const token = await auth.credentials.getToken();
      // if extracted token has expired, we request a new login flow
      if (new Date(token.expiresOn).getTime() < Date.now()) {
        logger.info(`Your stored credentials have expired; you'll have to log in again`);

        auth = await retryLogin(auth);
      }
    } else {

public async interactiveLogin(options?: InteractiveLoginOptions): Promise {
    let authResp: AuthResponse = { credentials: undefined, subscriptions: [] };
    const fileTokenCache = new SimpleFileTokenCache();
    if (fileTokenCache.isEmpty()) {
      await open("https://microsoft.com/devicelogin");
      authResp = await interactiveLoginWithAuthResponse({ ...options, tokenCache: fileTokenCache });
      fileTokenCache.addSubs(authResp.subscriptions);
    } else {
      authResp.credentials = new DeviceTokenCredentials(undefined, undefined, fileTokenCache.first().userId, undefined, undefined, fileTokenCache);
      authResp.subscriptions = fileTokenCache.listSubscriptions();
    }

    return authResp;
  }
