esp_littlefs: Unable to compile on S3, as not finding littlefs submodule, as not imported using component manager.

When building a project for ESP32 S3, in Visual Studio Code Insiders on Windows 10, the component manager fetches the joltwallet__littlefs component, and adds it to the /managed_components folder. The folder structure is correct, but for /littlefs … see image below. It appears not to import the submodule, so the /littlefs folder is empty…

So the build fails as it cannot find

#include "littlefs/lfs.h"

Is there something I must add to .vscode settings.jason. I have added:

"idf.enableIdfComponentManager": true,

Build error log follows
