Puppeteer not changing public ip on iproyal proxy servers on socks5 protocol

Question

I want to scrap this site http://cheapinsurancebyzip.info/medicare using puppeteer node js and proxy serevers from iproyal. When I scrap this using http or https protocol, its gives error. SO I have to use socks5 protocol for this, But its not changing my public ip.

This is my code if I use http

const launch = async (
  url = 'http://cheapinsurancebyzip.info/medicare',
  index = 1
) => {
  const puppeteer = require('puppeteer');

  const browser = await puppeteer.launch({
    executablePath: 'chrome-win/chrome.exe',
    args: [
       // ! Error: Socks connect tcp 168.xxx.xxx.xxx:xxxxx-> unknown error host unreachable
     // '--proxy-server=http://geo.iproyal.com:12321',


      // * NO error but ip remains same as before ( 58.65.164.138 )
      '--proxy-server=socks5=http://geo.iproyal.com:42324',



    ],
  });

  const page = await browser.newPage();
  await page.authenticate({
    username: 'myusername',
    password: 'mypassword',
  });

  await page.goto(url);
  console.log('page loaded');

  const axios = require('axios');
  const response = await axios.get('https://api.ipify.org');
  const publicIp = response.data;
  console.log('publicIp', publicIp);

  return;

  // browser.close();
};

I tried changing proxy servers of iproyal but it not worked. My Iproyal proxy servers are also getting proxy royal residential api of iproyal.
