Enabling soft deletion: `_deleted` value does not exist in my DynamoDB entries

[pcanas]

I was following the How it works section video on Datastore, and I realized that in the demo they were using the field _deleted which allowed for soft deletion. After a standard setup of my Datastore API, I cannot find this field, and I was wondering how I could enable soft deletion within my application.

Other default fields like __typename, _version, and _lastChangedAt exist in my DDB table.

This is an example of an item in my schema:

type Institution @model {
  id: ID!
  name: String!
  address: String!
  country: String!
  users: [User] @connection(name: "UserInstitution")
}

And the following is the transform.conf.json file (in case it is useful).

{
    "Version": 5,
    "ElasticsearchWarning": true,
    "ResolverConfig": {
        "project": {
            "ConflictHandler": "AUTOMERGE",
            "ConflictDetection": "VERSION"
        }
    }
}

Thanks for the help!
