Terminal Session connection between Micro Focus Rumba and Uipath

Hi All,

I am a beginner trying to implement Mainframe Automation using Uipath. When i start designing my workflow process and I add terminal session and configure it as below, the Wizard opens up correctly.

What should be the steps if i want to run this workflow again ? When i save my workflow in uipath and close rumba application and then again try to run the process it does not run.
How do we run the uipath main.xaml again and again so that my rumba is opened and my designed tasks are executed
