how to push guage matrices to pushgateway using https://github.com/siimon/prom-client nodejs client.

Although the library explain how to push like below:

const client = require('prom-client');
let gateway = new client.Pushgateway('http://127.0.0.1:9091');

gateway.pushAdd({ jobName: 'test' }, function (err, resp, body) {}); //Add metric and overwrite old ones
gateway.push({ jobName: 'test' }, function (err, resp, body) {}); //Overwrite all metrics (use PUT)
gateway.delete({ jobName: 'test' }, function (err, resp, body) {}); //Delete all metrics for jobName

but it pushed the value as timestamp.

I want same as guage the value part must have the numeric value and label as timestamp. It should be same as guage matrices.
