number format

Hi

I was reading this document to change the number format

https://docs.wpovernight.com/woocommerce-pdf-invoices-packing-slips/number-format-explained/

but I couldnt find the path to go to this setting.

I checked Woocommerce > PDF Invoice > General settings (and other tabs) but I don’t see the setting to change the number format.

Can you guide me on this?

Thank you
