Cad Converter missing? it is not in Omni.kit

I am trying to make a connector using cad converter, but actually when I go to omniverse kit, and go to extensions, it is missing.

I followed this guide

However I cannot find it anywhere. I am currently using Windows 11

omni.kit.converter.cad does not exists

How can I get Cad converter?

I found omni.kit.converter after downloading External App Templates, then going into extensions
