Selenium Ip Address Changing Code Not Working

I am trying to make selenium change a ip address but it isn't working. The ip addresses are taken from

const {Builder, By, Key, until} = require('selenium-webdriver');

const proxies = [
"47.243.167.134 :8889",
"154.236.179.233:1976",
"200.105.215.22:33630",
];

async function changeIP() {
 const proxy = proxies[Math.floor(Math.random() * proxies.length)];
const capabilities = {
'browserName': 'chrome',
'chromeOptions': {
  'args': [`--proxy-server=
}
};

const driver = await new Builder().withCapabilities(capabilities).build();

await driver.get("");
}

changeIP();
