Integration between Studio and Business Manager

Hello Eugene ...
I am really sorry, But I can not really understadn how to connect my Business Manager TEAM and my Studio 2019.

Once upon a time there was a plugin for BaccS but now ... If I look for such a thing in the SDL App Store I find 1 conncetor and a CONNCETOR and something I do not really understand if it is a plugin or a stantalon program itself. My Business Manager is the Team version and I would not like to experiment. I'd just like to understand which one of this I should run.

Thank You.
Pietro
