The Add Data Widget in Experience Builder supports kml files, but not kmz files. I find that kmz files are very commonly used, so it would be great if we could import them as well.
Users need to be able to add KMZs. Generally non-GIS users are using Google Earth and are sending/receiving kmzs. I have no need for literally any of the other file types. If you supported kmz, folks could be empowered to communicate and move across systems with partners of all kinds.
