I am using a shipping company in UAE called Icarry and they don’t have plugin in wix.
They have API integration only and they share this link with me:
We have a shipping rates plugin that allows to show rates from providers we do not support so this may be what you need eCommerce Shipping Rates Service Plugin
THis is a solution that must be coded and can be more advanced so if you end up needing to hire a developer, check our marketplace Professional Web Developers for Hire - Wix Marketplace
