SSO Authentication from terraform cloud to aws

I am done with setup of landing zone (aws control tower) and configured SSO authentication with google workspace and the users are able to login to aws console.

But how to connect terraform cloud to aws using SSO authentication as we are not managing users in IAM and using SSO only we need to authenticate with AWS cloud.

please help me with the process.

SSO is designed to help help people authenticate securely and simply with AWS. It isn’t any use for system usage.

If you were wanting to authenticate a system running within AWS you would use IAM roles, but as you are wanting to authenticate from a non AWS system you will need to use an IAM user.

Thanks for your reply.
For further I will connect with AWS support.
