Sync shipping rates from apps to shopify platform

[thongdv]

Hello everyone
I have an question :
I have created an app by react js, my app defined all rate of country corresponding to weight and price.
I see have one function in path Settings/Shipping and delivery/Manage Rates and Add rate "Use carrier or app to calculate rates" as image,

but i don't known, Is there any way to select my app to use my rate defined or Is there any way to sync data from app to shopify platform?

Thanks
