Getting next-auth-steam to work with create-t3-app

According to next-auth-steam's examples i should override jwt() and session() callbacks like this

jwt({ token, account, profile }) {
  if (account?.provider === PROVIDER_ID) {
    token.steam = profile
  }
  return token
},
session({ session, token }) {
  if ('steam' in token) {
    // @ts-expect-error
    session.user.steam = token.steam
  }
  return session
}

jwt({ token, account, profile }) {
  if (account?.provider === PROVIDER_ID) {
    token.steam = profile
  }
  return token
},
session({ session, token }) {
  if ('steam' in token) {
    // @ts-expect-error
    session.user.steam = token.steam
  }
  return session
}

https://github.com/Nekonyx/next-auth-steam/blob/master/examples/app-router-get-server-session/app/auth.ts#L17C7-L29C8 so I can access steam user data in session, i assume ? However this does not work in create-t3-app ( or maybe I am just missing out on something )

I did some changes that theoretically should fix the issue, 1. declared next-auth/jwt so it has steam property

declare module "next-auth/jwt" {
  interface JWT extends DefaultJWT {
    steam?: any; // temp: just to get it working
  }
}

declare module "next-auth/jwt" {
  interface JWT extends DefaultJWT {
    steam?: any; // temp: just to get it working
  }
}

2. minimally modified callbacks

jwt({ token, account, profile }) {
  if (account?.provider === PROVIDER_ID) token.steam = profile;

  return token;
},
session: ({ session, token }) => ({
  ...session,
  user: {
    ...session.user,
    steam: token.steam ? token.steam : null // yes, i added steam field to Session interface aswell
  },
}),

jwt({ token, account, profile }) {
  if (account?.provider === PROVIDER_ID) token.steam = profile;

  return token;
},
session: ({ session, token }) => ({
  ...session,
  user: {
    ...session.user,
    steam: token.steam ? token.steam : null // yes, i added steam field to Session interface aswell
  },
}),

Unlucky this did not resolve issue and I am getting following session error

Maybe someone who understands way better than me, could give some hints, what am I missing out on
