Observer Points to 3D Building Viewshed Analysis using 3D Analyst Toolbox

Hi,

I am trying to create a viewshed analysis from multiple cell tower locations to 3D buildings. In other words I need to be able to quantify how many sq. feet of each of building face has a direct view to a tower, and how many sq. feet do not. The 'Exploratory Viewshed Analysis' is exactly what I am looking for visually, with the green in the screenshot representing parts of the building reached by a tower, and red parts of the building not reached. But I am having trouble replicating this with the geoprocessing tools so I can calculate the surface area covered.

I've tried converting the 3D buildings into raster and using the Viewshed tool but I keep getting stuck. Any workflow guidance here is greatly appreciated!!

The tower data can be found here (assumed 35 feet above ground level for z value): DAS/Small Cell Locations - Public (arcgis.com)

The 3D multipatch building data can be found here: https://maps.bostonplans.org/3d/Bos3d_CityWide_Data/Bos3dModels_P20210830.gdb.zip
