Call hook

I noticed that PlayerSpawnedProp isn’t called when I use my tool to spawn something. How to call it?
[lua]
PlayerSpawnedProp(ply, ent:GetModel(), ent) – Attempt to call nil value.
hook.Call(“PlayerSpawnedProp”, ply, ent:GetModel(), ent) – Nothing happens.
[/lua]

hook.Call(“PlayerSpawnedProp”, GAMEMODE, ply, ent:GetModel(), ent)
