The final thing I'm missing in the PortableGit package for ARM64 is the Git Credential Manager Core. Because of this, when doing operations like git push from within a cmd/powershell terminal, results in:
PS C:\repos\test> git push
Username for 'https://github.com':
Notice the difference in the amount of items in the arm64/libexec vs mingw32/libexec:

I found a reference to git-credential-manager-core in please.sh, but not entirely sure where in the whole build process it is invoked. Could someone point me in the right direction as to where this is added to libexec? We should be able to use the gcmcore-win-x86 (x86) version on ARM because it can leverage 32-bit emulation.
Thanks in advance!
