example command: granted sso populate --sso-region ap-southeast-2 https://example.awsapps.com/start --prune
the prune argument is inactive due to its position. Ideally arguments should be parsed no matter which position they appear in.
If you move prune it works as expected
granted sso populate --prune --sso-region ap-southeast-2 https://example.awsapps.com/start
