Fix status: documented_behavior Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/aws/aws-cli/d22f2115447d212da4af5fc35e440ec7f960aad4/CHANGELOG.rst (changelog, unknown, documented_behavior): 2.22.0: 'Add support and default to the OAuth 2.0 Authorization Code Flow with PKCE for aws sso login'; later: suggestion to use --use-device-code; --redirect-port support added. - https://raw.githubusercontent.com/aws/aws-cli/d22f2115447d212da4af5fc35e440ec7f960aad4/awscli/customizations/sso/utils.py (official_docs, unknown, documented_behavior): --use-device-code uses the Device Code grant instead of Authorization Code; login prints 'If you are unable to open the URL on this device, run this command again with the option.'
