ICAO Flight Plan and STAR designators

[foghorn]

Sorry if this is a dumb question, I can't find this in the Aerad's otherwise excellent section on ICAO flight plans, and I'm racking my brain from the ATPL days.

I know that you don't put a SID designator in the ROUTE section of an ICAO flight plan, you just put the fix/navaid upon which the SID is based.

What do you do with a STAR? Do you just put the initial fix? Or the initial fix, then the STAR designator, and then the final or holding fix of the STAR as if it were an airway? Or something different?

Thanks for your help.
