Accessing second level key values in terraform

Terraform
1

I am doing the following in my terraform module:

data "vault_policy_document" "this" {

  dynamic "rule" { 
    for_each = {
      for p in var.policy.policy_content : format("%s-%s-%s", p.path, join(",", p.capabilities)) => p
    }

    content {
      path = rule.value.path
      capabilities = rule.value.capabilities
    }
  }
}

The variable is declared as

variable "policy" {
  description = "The policy to be created"
  type        = map(any)
}

and with a certain confidence, it is of the form


{
          + "policy-test-1" = {
              + policy_content = [
                  + {
                      + capabilities = [
                          + "read",
                          + "create",
                        ]
                      + path         = "/foo/lala"
                    },
                  + {
                      + capabilities = [
                          + "read",
                          + "create",
                        ]
                      + path         = "/bar/lala"
                    },
                ]
            }
        },

Is there a way to access the values of policy_content in my for loop?
