How do you get you Amazon listing to be advertised on Google shop sponsored ad section on Google?

I’ve asked this before and someone answered something like “it takes some pretty advanced backend coding to get this to happen” and some that said it’s not possible to get your Amazon listing advertised in the Google shop section.

First of all, it’s definitely possible and can’t be that hard. Every single search you make for a product ends up showing an Amazon listing in the Google shop section. There’s TONS of listings being promoted on Google shop. Plus it can’t be that sophisticated as there’s very small sellers utilizing this tactic. Does anyone know how to do this??
