Describe the bug

As far as I understood, every session always has a identity in it's response.
This is also the case in the openapi spec under the session, where identity and id are set to be required fields.
But apparently the javascript/typescript client does not generate it as such, and generates it as a optional field in the Session type. This causes issues in our project down the road, because we would either have to do unnecessary checks all over the place just to satisfy TypeScript in that reagard, or overwrite your internal Session type such that the identity is not optional.

Reproducing the bug

Create a typescript project,

1. Call toSession({...}) on a FrontendApi client instance.
2. Try accessing the session.identity.id attribute, which fails
3. Note that typescript is telling you that the "identity might be undefined"

Relevant log output

'session.identity' is possibly 'undefined'.ts(18048)
(property) Session['identity']?: Identity | undefined

@type — {Identity}
@memberof — Session

Additional Context

No response

Start by comparing the OpenAPI session definition, where identity and id are required, with the generated Session type used by FrontendApi.toSession. Trace the client generation input and output to find where identity becomes optional. Done means the generated TypeScript type reflects the required spec and session.identity.id no longer produces the reported error.
