Get data on form on right based on the selection from list on left by making a rest call

I want to implement something like this: where when a user selects an item from the list on the left, a REST service call is made and the output data is listed int the form on right side. I am adding a onClick action on list view that calls a microflow to get data (using the selected item name). What should be the data source for the form on the right side?   P.S. I do not have any persistable entity as I am integrating a legacy module

I think your right side should be a dataview with a ‘listen to widget’ that listens to your listview.

After your rest call is done you can just refresh the object from the listview and the output data should be shown.
