如何在创建局部变量时遍历terraform中的地图列表？

variable "my_map" {
  type = map(list(string))
  default = {
    key1 = ["value1", "value2"]
    key2 = ["value3", "value4"]
  }
}

locals {
  my_local_var = {
    for key, values in var.my_map :
    key => values
  }
}

{
  "key1" = ["value1", "value2"]
  "key2" = ["value3", "value4"]
}
