Analyzing Multicast on Tap interface?

[Unibw]

Is it possible to analyze multicast traffic on a tap interface?

I am unable to commit a multicast policy bound on a tap.

Tap {
  to multicast;
  from Tap;
  source any;
  destination any;
  source-user any;
  category any;
  application any;
  service application-default;
  hip-profiles any;
  action allow;
}

Commit error:

In VSYS vsys1 from zone Tap of type tap and to zone multicast of type unknown are incompatible in security rule Tap
Configuration is invalid
