How to support TLS 1.3 using SwiftNIO?

I'm working on a traffic grab app on iOS, I will intercept the traffic through VPN and then initiate the request again through man-in-the-middle attack.

See TN3120: Expected use cases for Network Extension packet tunnel providers. If you use this outside the context of a Network Extension, does this work as intended?

A few apps do this successfully, e.g. Charles. Notably there is a difference between intercepting the traffic through an actual VPN (which requires TCP/IP decoding) and just using the extension to inject a proxy configuration (which then only works for HTTP/HTTPS I think).
