Question: How to create an IAM policy using hclwrite

Hello

We are trying to create terragrunt files programatically with hclwrite and having some difficulties with writing iam policies. What I am trying to achieve is this terragrunt.hcl file for an s3 bucket.

- How can I create the policy and add it to the inputs as an attribute?

```
include {
path = find_in_parent_folders()
}

locals {
common_vars = yamldecode(file(find_in_parent_folders("common_vars.yaml")))
name = "product-images"
}

terraform {
source = "../../../../common//terragrunt-base/modules/terraform-aws-s3-bucket"
}

inputs = {
bucket = "${local.common_vars.namespace}-${local.common_vars.environment}-${local.name}"
policy = <

No repository file or test is named. Start by reading the hclwrite API and searching existing examples or tests for constructing attributes and heredoc-like values; done means identifying a supported way to build the policy and assign it to the inputs attribute, or documenting that limitation.
