I'm pulling out my hair over this, but I cannot seem to find a solid answer over which shopify apps can I use for a new storefront built on Hydrogen 2.0 and Shopify Plus
I can see this page which seems to indicate it is possible "to extend hydrogen build with apps": https://apps.shopify.com/collections/apps-to-extend-hydrogen-build
But I can see no indication on how would I use an app like this (which is created by shopify): https://apps.shopify.com/search-and-discovery
It's fine if the app only provides admin functionality and I need to access the data it creates through APIs (like related/complementary products), but I cannot find any documentation on if it is possible or not.
And when searching for Apps, is it possible to determine (from the "apps store") if said app is usable with hydrogen or is it only for liquid themes?
Hydrogen is nothing but a front-end for Shopify. Anything you're doing with Hydrogen has an analog with the standard theme template system. If an App helps the non-Hydrogen Shopify store front, there is nothing stopping you from using the same App. Why are you pulling out your hair?
