Imported extension cannot be found in python script

[noonchen-ni]

I imported an extension.zip in GUI and the log shows the extension is installed in cache dir:

However, in python script the path above is not one of the default paths:

Is it an expected behavior? As a user, when an extension is imported, I expect the extension to be "install" to its search paths.

Currently I have to explicitly specify the path to get it loaded, it works but not very convenient.

extmgr = get_app().get_extension_manager()
extmgr.add_path("/home/xm/.local/share/ov/data/Kit/Isaac-Sim Full/5.0/exts/3")
extmgr.refresh_registry()
