Answer 1

Under corporate proxies we will face issues like this.
The 407 Proxy Authentication Required is an HTTP response status code indicating that the server is unable to complete the request because the client lacks proper authentication credentials for a proxy server that is intercepting the request between the client and server.
Option 1 : Try using selenium-standalone npm package. This is similar to webdriver-manager.
https://www.npmjs.com/package/selenium-standalone
Install this package globally
npm i -g selenium-standalone
Then to download/install the drivers
selenium-standalone install
Then to start the server
selenium-standalone start
(Or)
