Migrating from Amplitude to Mixpanel: Creating a Domain Proxy with AWS API Gateway

Hi, I'm new in Mixpanel, I would like to migrate from amplitude to Mixpanel. But I have an issue. I created domain proxy for amplitude by only using AWS API GATEWAY. But it seems there is no guide to make proxy using AWS API GATEWAY for Mixpanel. Is it possible to make domain proxy by only using API GATEWAY?
