Is allowed authentication proxy?

[MacKey-255]

Hello, I am trying to make a traffic redirector through a Socks5 proxy and I loved your project. It does exactly what I'm looking for, but I don't know if it allows the use of Socks5 proxy authentication. So is authentication allowed?
Because I need to redirect all traffic from a specific program to a Sock5 proxy with authentication that has internet access. SAlu2s
