How to use the openid-client.Issuer.useRequest function in openid-client

const { Assertion } = require("../../assertion");
const { BasePlugin } = require("../../plugin");
const { Issuer } = require("openid-client");
const jwt = require("jsonwebtoken");
const oauth2 = require("simple-oauth2");
const queryString = require("query-string");
const request = require("request");
const URI = require("uri-js");

Issuer.useRequest();
Issuer.defaultHttpOptions = { timeout: 10000, headers: {} };

const exit_failure = function(message = "", code = 1) {
  if (message) {
    console.log(message);
  }
  process.exit(code);
};

const issuer_encrypt_secret =
  process.env.EAS_ISSUER_ENCRYPT_SECRET ||
  exit_failure("missing EAS_ISSUER_ENCRYPT_SECRET env variable");
const issuer_sign_secret =
  process.env.EAS_ISSUER_SIGN_SECRET ||
  exit_failure("missing EAS_ISSUER_SIGN_SECRET env variable");

module.exports = function(app, passport, provisioning) {

  var fs = require('fs')
