HIKVISION ISAPI iDS-TCM203-A

A am trying to get the car license plate Hikvision iDS-TCM203-A by using ISAPI. The camera admin panel allow you to recognize plate number by using the next button

The problem is I need to get that value in the NodeJS application. I have subscribed to /ISAPI/Event/notification/alertStream long polling channel, but sometimes it does not emit the license plate value from a car in camera viewport

const request = require("request");
const xml2js = require("xml2js");

const { errorData } = require("../utils/errorData");

const parser = new xml2js.Parser();

const createListener = (requestUrl, { auth, logger, onData } = {}) => {
    const handlePackage = (data) => {
        try {
            logger.log(JSON.stringify(data));
            onData(data);
        } catch {
            console.log("not json :-(");
        }
    };

    return request
        .get(requestUrl)
        .auth(auth.username, auth.password, false)
        .on("response", function (response) {
            if (response.statusCode === 200) {
                console.log("Listening");
                logger.log("Connection opened");
                response
                    .on("data", function (chunk) {
                        parser.parseString(chunk, function (err, result) {
                            if (!result) {
                                return;
                            }
                            handlePackage(result);
                        });
                    })
                    .on("error", (error) => {
                        logger.log(`Listener error: ${JSON.stringify(errorData(error))}`);
                        process.exit(-1);
                    })
                    .on("close", () => {
                        logger.log("Connection closed");
                        process.exit(-1);
                    });
            } else {
                logger.log(`Listener error (endpoint): code ${response.statusCode}`);
                process.exit(-1);
            }
        })
        .on("error", function (error) {
            logger.log(`Listener error (request): ${JSON.stringify(errorData(error))}`);
            process.exit(-1);
        });
};

module.exports = { createListener }

To solve the missing license plates problem I want to spam the detect request for each 1 second. I need to get the endpoint to read all license plates from a current capture frame. The reference code is

const main = async () => {
  await pb.admins.authWithPassword(POCKETBASE_ADMIN_EMAIL, POCKETBASE_ADMIN_PASSWORD).catch(() => {});

  while (true) {
    const image = await captureImage();
    const cars = await captureLicensePlate(image);
    if (!cars.length) {
      fs.unlinkSync(`./public/image/${image}`);
    }
    for (const { licensePlate, bbox_bottom, bbox_left, bbox_right, bbox_top } of cars) {
      logger.log(`DETECT CREATED licensePlate=${licensePlate} image=${image}`);
      const dto = {
        licensePlate,
        bbox_top,
        bbox_left,
        bbox_right,
        bbox_bottom,
        image,
      };
      console.log(JSON.stringify(dto, null, 2))
      await pb.collection("DETECT").create(dto);
    }
    await sleep(DETECT_TIMEOUT);
  }
};

I have tried a lot of code to achieve required behavior. The /ISAPI/Traffic/channels/1/licensePlateAuditData/record?format=json and /ISAPI/Traffic/channels/1/vehicleDetect/plates are giving me 401 no matter if auth credentials works for /ISAPI/Event/notification/alertStream. Could you give me an example which just works well, not googled solution which will not work especially with this camera. Maybe steps to reproduce to setup the admin panel?
