BUG: Configuration Migration Tool permission denied issue

I think there is some sort of bug while using CMT tool in GCC. I have 2 different AD accounts to login into Power Platform. One is daily driver which does not have SA role but that's what i use to login into my Windows. The second account is privileged account and has SA role. When i launch cmt using PAC CLI and try to login with my privileged account, it displays the list of environments that my privileged account have access to. But once i select the environment from the list and click on 'Create Schema', i believe it uses my Windows account (daily driver without SA role) since i get 'You don't have permission to perform this action' error message.

I downloaded the CMT tool from nuget and replicated the same process but i didn't get permission error message and was able to migrate data.

Start by reproducing the PAC CLI CMT flow in GCC with separate daily-driver and privileged AD accounts, selecting an environment and choosing “Create Schema.” Compare that behavior with the NuGet CMT flow described in the issue. Done means the selected privileged account is used consistently and the permission error no longer occurs for an account with the required SA role.
