Provider Permission Error with new AWS SSO Setup

Hi there,

after switching the AWS SSO setup to the new session based configuration, the provider does not work anymore.

Terraform Version

Terraform v1.8.3 on darwin_amd64

provider registry.terraform.io/idealo/controltower v1.3.0

Affected Resource(s)

controltower_aws_account

Terraform Configuration Files

provider "controltower" {
  region = "eu-central-1"
}

AWS Configuration

[sso-session session]
sso_start_url = https://[REDACTED].awsapps.com/start#/
sso_region = eu-central-1
sso_registration_scopes = sso:account:access
[default]
sso_session = session
sso_account_id = [REDACTED]
sso_role_name = [REDACTED]
region = eu-central-1

Expected Behavior

The resource is planned and can be applied

Actual Behavior

│ Error: error configuring Terraform ControlTower Provider: Error creating AWS session: profile "default" is configured to use SSO but is missing required configuration: sso_region, sso_start_url

Steps to Reproduce

terraform plan

Important Factoids

I assume that this could be solved by creating a new release of this provider that contains an updated version of the AWS SDK.
