Need Help with SSl Private Proxies & OpenVpn

Hello. I have bought 20 Private proxies from SSl Private Proxies and I' am trying to connect to each one of them using OpenVpn, but the manual connection doesn't work. I know that I can't connect to each using a Proxy Config file, but I can't find it anywhere or how I should create one of this file.
Can you please help me with this ?
Thank you.

You mean SSL private proxies?

And why you want to connect to proxies via openVpn?

Instead use the IPs directly in browser via addon.

Your provider should supply you with API integration.
I will suggest configuring them on your browser unless
if you are using a tool/software.
