Why arent NPC's working

I know I have already created a thread for this but now I have a completely different problem and the other thread is gone.

I made a addon and a entity (garrysmod/addons/NPCPickupJob/lua/entites/npc_supplydealer/init, cl_init, shared.lua) and pasted the exact code from a basic scripted npc example (https://maurits.tv/data/garrysmod/wiki/wiki.garrysmod.com/indexde03.html).
If I open the spawnmenu and go to NPCs or even Entites my npc isnt there. I tried so many different things over the past day and I cant even get it to spawn in the menu. I am litterly just wanting a npc that you can spawn and place somewhere and it just stands there.
If someone can please help me that would be great.

use console commands to spawn it

npc_create <internal npc name> I think it is

I got a error




] npc_create npc_supplydealer
Attempted to create unknown entity type npc_supplydealer!




Its a scripted entity, you need to use ent_create in that case, or ents.Create if you doing it in Lua

Tried both and its still not working.

Put the folder “npc_supplydealer” and it’s contents inside of …/common/GarrysMod/garrysmod/lua/entities/
