Loading geometry from command line

Hello there,
I just installed Netgen on my MBP. From the command line I can open it from command line with

netgen

If I’m in the folder containing the geometries, I can open one, e.g. File → Load Geometry → sculpture.geo

But I cannot do this from the command line using

netgen sculpture.geo

(netgen opens but geometry does not load).

At this point I have not added to my bash start up file the following: export PYTHONPATH=$PYTHONPATH:/Applications/Netgen.app/Contents/Resources/lib/python3.8/site-packages:.
export NETGENDIR=/Applications/Netgen.app/Contents/MacOS
export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:$NETGENDIR
export DYLD_FRAMEWORK_PATH=$DYLD_FRAMEWORK_PATH:$NETGENDIR/…/Frameworks
export PATH=$NETGENDIR:$PATH

When I do, and I again call

netgen

I get the error below. Can you provide some advice on what to do?

dyld: Library not loaded: /Library/Frameworks/Python.framework/Versions/3.8/Python Referenced from: /Applications/Netgen.app/Contents/MacOS/netgen Reason: image not foundzsh: abort netgen

ALSO: are you aware that this link is broken: Getting started with Netgen/NGSolve — NGS-Py 6.2.2302 documentation

although this one works: Getting started with Netgen/NGSolve — NGS-Py 6.2.2302 documentation

Thanks!
