However, part of RFC 5077 remains applicable:

   https://tools.ietf.org/html/draft-ietf-tls-tls13-07#section-6.3.11

       The ticket itself is an opaque label.  It MAY either be a
       database lookup key or a self-encrypted and self-authenticated
       value.  Section 4 of [RFC5077] describes a recommended ticket
       construction mechanism.
