Export inventory quantities dynamically with shopify flow

Hi guys,

I am new to Plus and i am stuck with some liquid issue.

In details i want to build a custom inventory manager system for my POS via Shopify Flow and Google spreadsheet, more in deep i have my inventory divided into POS and Online channel and i only get as a result of my liquid function the Name of the variants and the Combined quantity of POS and Online, instead of just the POS quantity (my physics store inventory).

Right now i am using this formula:

{% for variants_item in product.variants %}
{{variants_item.displayName}}
{% endfor %},
{% for variants_item in product.variants %}
{{variants_item.inventoryQuantity}}
{% endfor %}

I need to update this formula to get only the information of the POS quantity and not the combination of Online and POS. Hope that i explained myself well, and hoping to have an answer shortly.

I am leaving you guys the PPT where i explain better my problem, i think this can help a lot of people building a dynamic inventory manager without any paid app or so.

Thank you very much
