output "iam" {
value = data.ovh_iam_policies.my_policies.policies
}

Outputs:

iam = toset([
"1a016c5f-bb43-4069-803d-daab0f22319b",
"d7daf48e-ba7e-4373-aa4b-b6a9dcace1f3",
])

data "ovh_iam_policy" "my_policy" {
id = tolist(data.ovh_iam_policies.my_policies.policies)[0]
}
```

Display all the available resources in your TF state

```
terraform state list
```

Output:

data.ovh_iam_policies.my_policies
data.ovh_iam_policy.my_policy

```
