Hi 🙂

I am trying to understand if it´s possible to generate locally a custom token on a project that I´ve bootstraped with the command:

`daml new create-daml-app --template create-daml-app`.

Since the SDK version being used on the project is SDK \>= 2.0.0, the template code will use the following format for the token payload:

```haskell
{
  "sub": "alice",
  "scope": "daml_ledger_api"
}

```

How can i setup the readAs and actAs like on the example under through the Front End?

```haskell
{
  "exp": 1669008104.608,
  "https://daml.com/ledger-api": {
    "ledgerId": "gambyl-sandbox",
    "applicationId": "da-marketplace",
    "actAs": [
      "Alice"
    ],
    "readAs": [
      "Alice",
      "Public"
    ]
  },
  "party": "Alice",
  "ledgerId": "gambyl-sandbox",
  "partyName": "Alice"
}

```

Thank you in advance 🙂

Hi @Joao_Freitas, from Daml 2.0 we have a new concept of _user_ managed by the `UserManagementService`. Instead of providing claims in the token itself, you map the off-ledger concept of user (which is the `sub` field in the audience-based or scope-based tokens) to its on-ledger role as a party.

You can read more about tokens in the [page about authorization in our documentation](https://docs.daml.com/app-dev/authorization.html).

As for how to access the `UserManagementService`, you can do so both through the [Ledger API](https://docs.daml.com/app-dev/grpc/proto-docs.html#com-daml-ledger-api-v1-admin-user-management-service-proto) (e.g. using the [Java bindings](https://docs.daml.com/app-dev/bindings-java/index.html)) or using the [HTTP JSON API off-ledger integration](https://docs.daml.com/json-api/index.html#create-a-new-user).
