Automatically running Vision Flow


I have a Magician with Vision Kit. I would like to configure the software to automatically run a flow when the computer logs on. I have everything working to load the app automatically, and the flow loads/runs automatically - but I can’t figure out how to have it connect to the robot (in this case on COM4) automatically.

So, how do I either programatically (in vision studio), via a flow, or a saved setting somewhere tell it to just use and connect to magician on COM4 (which is where the robot is)?
