Custom Icons - source file not available


I’ve tried following this guide to add a couple more icons to the theme, but unfortunately, I have no folder named “fonts” in “entrada”:

You will need to import the wp-content >> themes >> entrada >> fonts >> icomoon >> entrada-icomoon.json file first, and then import your own icons json file.

Neither in the “icomoon” folder is there any entrada-icomoon.json file.

Could you please provide this file so I can add new icons without losing old ones?
