Hello, would someone show me example codes of how to add glow and aura to the model of a player who is in possession of a extra item in a ZM mod?

For example, i want all humans who possess the following extra item:

Code:

...to emit glow and aura while having the item. Since the item lasts only for a single round and gets removed when an infection grenade is used on the human, the glow and aura should, too, disappear once the round ends or the gas mask is removed using an infection grenade.

Thanks in advance. :)
