Shopify Watch Orders does not see POS orders

I am trying to create a simple scenario to watch all orders from Shopify and put it in to a google sheet (and then eventually into other modules). The template they provide and all testing I’ve done, does not retrieve orders from my POS system.

  1. Is there something I’m missing using the Shopify Watch Orders trigger?
  2. I read there is a API way to do that… is there someone with knowledge on how to do this who can create that for me?
