Create google storage bucket using terraform and set life cycle rule for the specified buckets

Question

I have a terraform module to create some storage buckets with specified permissions to users now I need to specify some life cycle rules for some of the buckets, and I need to map between two variables as follows:

variable.tf

variable "buckets" {
  description = "List of buckets"
  type        = list(string)
  default     = []
}

variable "bucket_deletion_rules" {
  description = "Ad-hoc Bucket deletion rules"
  type        = set(object({}))
  default     = [{}]
}

bucket.tf

resource "google_storage_bucket" "data_bucket" {
  for_each                    = toset(var.buckets)
  name                        = each.key
  project                     = var.project
  location                    = var.region
  uniform_bucket_level_access = true
  versioning {
    enabled = false
  }

  dynamic "lifecycle_rule" {
    for_each = var.bucket_deletion_rules
    content {
      action {
        type = "Delete"
      }
      condition {
        age  = lifecycle_rule.value
      }
    }
  }
}

The above code does not work correctly! The idea is to define variables like this:

  buckets = [
    "bucket-mhmd-test1",
    "bucket-mhmd-test2",
    "bucket-mhmd-test3"
  ]
  bucket_deletion_rules = [
    {
    "bucket-mhmd-test1" = 50
    "bucket-mhmd-test2" = 10
    }
  ]

I've tried to put a nested for_each inside the dynamic, but I couldn't make it possible to compare the bucket names with bucket deletion rules. So now how I can define the variables and do the equalization between that two variables to apply the rules to the desired buckets?
