Getting conversion from page the contains at least 2 products

Hi, I am trying to create a page with 2 products on it, and I want that when I add them to the cart I will see conversion in Google Ads Conversion tracking.

I tried to play with the code, assign product variable in liquid:

{% assign product = all_products[‘product-xxx’] %}

and create new Shopify.OptionSelectors(‘productSelect’)

But still I don’t see any conversion via Tag Assistant Legacy.

Is there a way to do that?
