Deploy helm charts one at a time using loop

Terraform
1

Terraform version: v1.2.8
Helm version: v2.6.0
Kubernetes version: v1.24.2

variable.tf

variable "appcore" {
  description = "Core Applications"
  type        = set(string)
  default     = [
    "core-app1",
    "core-app2",
    "core-app3",
    "core-app4",
  ]
}

main.tf

resource "helm_release" "core" {
    for_each = var.appcore
    name     = each.value
    chart            = "${var.CHART_REPOSITORY_NAME}/${each.value}"

    values = [
      "${file("${var.values_file}/${each.value}.yaml")}"
    ]
}

This works fine except that the applications are deployed in parallel. Any suggestions on how these applications can be deployed one at a time using a loop?
