Sorry if this is a dumb question - I'm just getting started with AWS - I've installed the AWS CLI utility on Windows, and configured it with my access key and secret. The command "aws --version" says "aws-cli/2.8.10 Python/3.9.11 Windows/10 exe/AMD64 prompt/off". I'm trying to run "aws assume-impersonation-role" as documented here:

https://docs.aws.amazon.com/cli/latest/reference/workmail/assume-impersonation-role.html

but I get the error "invalid choice". The list of valid choices has nothing like what I'm looking for. Is there some extension or add-on I need to install?

Just to check the obvious, are you doing:

aws assume-impersonation-role --organization-id … --impersonation-role-id …

rather than the intended

aws workmail assume-impersonation-role --organization-id … --impersonation-role-id …

?
