I've not used Dancer2::Session::Cookie, but I know the following works for the
YAML session engine. Therefore, it might be worth trying the generic
cookie_duration parameter instead:

      session_dir: "/tmp/dancer-sessions"
      cookie_duration: 3600

To set a cookie:

    cookie MYCOOKIE => 'value', expires => '+2h', domain => $cookie_domain;

(I guess the domain is optional - I've just copied that from existing code)

To get a cookie:

    my $code = cookie 'MYCOOKIE'
