Access encoded JWT from Session instance

[LeoBorai]

When implementing callbacks I'm wondering if access to the encoded JWT would be possible.
As of now I understand that the session callback exposes session, user and token (the decoded one), but
I'm wondering if access to the encoded token is possible.

Something like:

    async session({ session, user, token, encodedToken }): Promise<Session> {
        // -- snip --
    }

My goal is to attach extra data to my Session which relies on using the JWT signed by NextAuth. So instead of having to retrieve such JWT manually I could take it straight from the Session instance when using either useSession or getSession.

we don't expose the raw token to the frontend, but you can read it on the backend using getToken({ raw: true })

Also, you cannot modify the session directly from the client, since the session is saved in an HttpOnly cookie.

There is a discussion on #2269 to make updating the session easier
