API type of Socks5 proxies: How to add password and username?

Found and ‘started’ to use an affordable socks5 proxy service to find out that they aren’t using regular usernames and passwords to protect their proxies, instead they use API.

The problem is, that I need a username and password in order to use these proxies for tools I use.

Any idea how to convert these API proxies into username and password types of proxies?
