Is there a way to decode a field to export the KMZ, that is stored in Base64

Hello, I have a field in a database where KML's are uploaded and stored in Base64. Is there a way to export those and convert them to KML within FME? My end goal was to convert to KML, then covert them to shapefile for a Portal Layer. For example attached is one of the files encoded that I confirmed is a KML by manually decoding it outside of FME. I tried the BinaryDecoder transformer, but I wasn't sure what to do with the result.
