Packaging for ios from windows pc

Hello,
I am trying to test a project on iphone. I have been using IPP to generate key pair. I downloaded the certificate from apple site. But in Unreal editor> Project setting it shows No valid certificate found.
(I also read that the ios quick start doc on unreal site is outdated). Anyone who can help me figure how to resolve this issue?

This video was very very helpful to me: 16 - iOS Set-up and Development - YouTube
i hope this will help you

Have you figured it out?
