Where are Extensions stored in Libreoffice for Mac OS?

I used Extension Manager in LibreOffice on Mac OS X El Capitan 10.11.6 to install an Extension. I tried installing for “All Users”, and installing “Just for me”.

Where are such extensions stored, on the Mac edition of Mac OS X?
Where are these locations documented?

I see Extensions documentation in the OpenOffice.org Developers Guide, but I haven’t yet found documentation of these locations.

I remember reading one instruction which said, look in the LibreOffice Preferences dialogue, under LibreOffice… Paths… BASIC (or Macro), but I see no such entry under “Paths used by LibreOffice”.

Ciao, did you see in the user folder of LO user profile? [Tutorial] User profile
