How do hyena treat their dead?

I know that elephants will spend several days with their dead in their version of a wake, and lionesses mourn over their cubs. But what about hyena?

I know hyena are a matriarcal pack society, but what do they do when one of their own dies. Is there a mourning period? Do they eat their fellows? I’ve been googling all morning and go only find facts about why they laugh or how most cubs die at birth due to suffocation. But nothing on their behaviors or reactions to their kin’s death.
