+// IMPORTANT: The provider in this package does not initiate or perform the AWS SSO login flow. The SDK provider

+// some other mechanism. The provider must find a valid non-expired access token for the AWS SSO user portal URL in

+//
+//  sso_account_id
+//  sso_region
+//  sso_role_name
+//  sso_start_url
+//
+// For example, the following defines a profile "devsso" and specifies the AWS SSO parameters that defines the target
+// account, role, sign-on portal, and the region where the user portal is located. Note: all SSO arguments must be
+// provided, or an error will be returned.
