Problem combiniong values from 2 array elements, deep in complex array

Having an impossible time simply concatenating the values for Content element within this array. All in a single bundle. The bundle containing the array comes out from an aggregator.

Not sure if I need to iterate through the array? Or use Text Aggregator? Or some complex Join array function/formula. I’ve tried all of them with either no input/output, or a single element in the output, but not both array elements.
