How renew greenlock-express certificates forcefully at any time?

I have CA certificates files in “greenlock.d/live/URL_PATH/”. It’s expiration date is Aug 2022.

But I want to renew them right now to check whether they are renewing or not. Please suggest me how can I renew them at any time?

What I have done:

I have tried number of solutions like:

• Tried Some commands
• Changing renewal time (“renewAt”) in “greenlock.d/config.json”

Code:

app.js

'use strict';

var app = function(req, res) {
    res.end('Hello, Encrypted World!');
};

module.exports = app;

server.js

'use strict';

var beapp = require('./app.js');

require('greenlock-express')
    .init({
        packageRoot: __dirname,
        maintainerEmail: "EMAIL_ID",
        configDir: './greenlock.d',
        cluster: true
    })
    // .serve(beapp);
    .ready(httpsWorker);
function httpsWorker(glx) {
    var httpsServer = glx.httpsServer(null, beapp);
    httpsServer.listen(443, "0.0.0.0", function () {
        console.info("Listening on ", httpsServer.address());
    });
}

greenlock.d/config.json

{
  "defaults": {
    "store": {
      "basePath": "./greenlock.d",
      "module": "greenlock-store-fs"
    },

      "http-01": {
        "module": "acme-http-01-standalone"

      "altnames": [

    }
  ]
}
