First time setting up ESP32 board (Windows 11 , with cp210x drivers installed)

I am following this guide : micropython setup

In DOS , I run esptool version shows esptool.py v4.7.0

The guide says to run esptool.py --port /dev/ttyUSB0 erase_flash
But I don’t have esptool.py on my c: drive and I get this error:

‘esptool.py’ is not recognized as an internal or external command,
operable program or batch file.

I tried both pip and pip3 install esptool . Any tips?
