Hi, I'm trying to follow this tutorial here: https://www.ory.sh/docs/identities/session-to-jwt-cors#json-web-token-claim-mapper This is the template example:

local claims = std.extVar('claims');
local session = std.extVar('session');

{
  claims: {
    foo: "baz",
    sub: "this can not be overwritten and will always be session.identity.id",
    schema_id: session.identity.schema_id,
    aal: session.authenticator_assurance_level,
    second_claim: claims.exp,
    // ...
  }
}

In the claims object do we have to repeat all the default claims if we want to keep them? e.g. in the example there is no

claims.nbf

even though it is in the default claims - will the nbf claim still be in the example?
