Organization instance Identity Center
As mentioned initially here I was having trouble finding a way to enable organization instance of Identity Center using some form of automated way ( either through aws cli, or cdk, or whatever).
Back then, I did not enable it, hoping I could find a way to do it using code. Since then, i’ve spent some time researching this, and I found some documents ( which I lost…) that seemed to imply this can only be enabled manually using the AWS Console. So going to do this now.
