await auth() don't trigger session callback

[killjoy2013]

using magic link with Resend & Prisma with "next-auth": "^5.0.0-beta.23"
I'll use session callback to check if session expired. If so, I'll update Session table & session object with new expiration. So far so good, however, in middleware when check session with
const session = await auth()

session callback is not triggered & auth() returns null.
How can I force to trigger session callback?
