I am trying to identify a single row in a grouping. So in the grouping the first group has 4 unique rows, second group has 3 unique rows but then the third only has one unique row. I need my output to show me all of the rows in the grouping that are a single unique row. I cannot figure this out or find any solution in the forum.
Here is my current Workflow

The output puts the numbers for grouping

Any assistance is greatly appreciated!
