latest version is 1.0.2 (from Feb 2023) https://pypi.org/project/cloudformation-cli-typescript-plugin/#history
thus when using the cfn tool to generate a new typescript based resource, it is still generating node14.x codebase (that requires manual work to get it up to date)
I believe the github action that should handle the release is broken https://github.com/aws-cloudformation/cloudformation-cli-typescript-plugin/actions/runs/9452490198
