Sketchup 2016 Pro - finding & deleting money-hungry .rbz file

New win 11 computer, installed my Sketchup 2016 Pro edition. After tossing my old computer I realized I hadn’t migrated my Sketchup plug-ins. In searching the Warehouse for the free .stl importer I downloaded/installed: “SimLab_STL_Importer_9.0.0.rbz”

I don’t want this file but I can’t find it to delete it. I no longer see it in my “Extensions” but now I get an error message every time I boot Sketchup telling me it didn’t load. Where does that file live so I can delete it?

Disregard my query, I took care of it
