Keyword for Storage class for storage class as : Glacier Instant Retrieval

I have written a terraform code for setting up a lifecycle policy for storage class as : Glacier Instant Retrieval I am getting the following error. Can anyone help me with the proper keyword for this storage class.

resource "aws_s3_bucket_lifecycle_configuration" "trackonomics_raw" {

bucket = "cn-dse-affiliate-prod"

rule { id = "EvergreenTrxDeltaArchivalPolicy" status = "Enabled"

transition {
  days          = 90
  storage_class = "GLACIER_IA"
}

filter {
  prefix = "trackonomics/raw/"
}

} }
