Automate dialing calls for S4B on macOS

I'm currently using Skype for Business (v16.12.75) and as an end user, I wanted an easy way to dial-into conference calls which usually involves the main number and then passcode. I wanted to see if there was a way to automate the actual calling from either the CLI/API on macOS system. 

I've done several searches and although things like Skype4Py came up (didn't work for me) or results were outdate or only applicable for Windows only systems.
