After some investigation i can only say that this PR is CURSED.
Can try to recreate, but not sure after hxcpp repo ignores me too.
I'm also tried to setup azure for fork, but Build.Repository.Uri and Build.SourceBranchName vars is not enough? Instructions in tests/README would be nice.
My error is An error occurred while loading the YAML build pipeline. Variable group was not found or is not authorized for use. For authorization details, refer to https://aka.ms/yamlauthz.

I remember having the same issue in my fork, but I don't remember how I fixed it. Maybe @andyli can help?
