I would call to your attention the options available if you select Master Details on the Operations tab. This would allow for model dialogue on click. Then you could customize a flow action to display values to the end user. As one example.
Another option might be to put a button on each row that on click fires an action. When you configure the button you go to the actions tab and there are specific actions for "Lists". Variety to choose from. That information is also in the above help article.
To give you some ideas take a moment to explore the UI Gallery. Designer Studio>User Interface>UI Gallery. There are examples of Repeating grids with actions on the rows.
