VS Team explorer hitting 403 error on AWS Codecommit

i am using a lambda account to create/clone a repository and the account has the AWSCodeCommitPowerUser and AWSLambda_FullAccess policy. However, it is hitting 403 error but the initial folder will be created. I have followed the guide from this link (https://docs.aws.amazon.com/toolkit-for-visual-studio/latest/user-guide/using-aws-codecommit-with-team-explorer.html). The issue starts after clicking OK at 'Creating a Repository'. Inside my lambda account, there is a HTTPS Git credentials for AWS CodeCommit, but VS does not prompt me for that. The region is correct as well. How can i fix this issue?
