I'm using Magento 2.3.4 community edition and need to know the files and locations to add product schema markups for product name, price, condition, long description, availability, brand, sku, product website link, and image. Google is not locating this info when publishing my products.
The current Magento help files do not show the updated file structure. I assume the files I need would be under /vendor, but I don't know exactly where to go and a search for the files the instructions mention are not found. I did download and install an extension that should apply this for me and it's not working either, so I'd rather be able to add the code myself.
If there is a different file location for smartphone setup, please point me in the right direction for that file, too. Thanks.
