Intercept between entering postage details and shipping price

Hey guys, I need to calculate shipping based on weight and distance of the item.

I would like to add my own logic between where the user enters their zip/post code and the calculation of the shipping, essentially when they click continue to shipping.



I have tried using webhooks, but this seems like only 1 way communication.

is the correct feature app extensions?

are there any examples on the internet for this?

I am also really interested in this and hope there is a way to hook into when the user clicks on Continue to Shipping to access various pieces of data.
