Several problems with HikaShop App

Hi, I have several problems associated with HikaShop App. Since my partners will use variants instead of creating individual products, there are several problems. The problem is to extract information about an image, description, category and vote. Instead of the information being taken from the variant, it must be taken from the base product (product_parent_id). I also want to ask how can extract price with VAT as it shows price without VAT.
