problems when flashing esp32 from MacOS

[sgrizzi]

After going through the installation procedure, when I try and flash the esp32 using the command:
node_modules/.bin/lowsync flash --port=/dev/cu.usbserial-0001 --init
I get the following error:

env: python: No such file or directory

*** esptool cannot be used.
Please check if you have Python installed.

I am runnning MacOS Monterey 12.6.3. Python3 is installed and working. So is the esptool.py tool.
How can I get lowsync to find the correct python version? Or can I somehow bypass lowsync and use esptool directly?
Rgds.
