Hello, im sorry, you check this topic?

https://umod.org/community/building-workbench/49057-notification-without-permission

even players without rights receive a notification when installing a workbench that the workbench works for the entire building

I will duplicate the code here, which I use after the last update, well, in that topic it was inserted crookedly :(

        private void OnEntitySpawned(Workbench bench)
        {
            //Needs to be in NextTick since other plugins can spawn Workbenches
            NextTick(() =>
            {
                BuildingData building = GetBuildingData(bench.buildingID);
                building.OnBenchBuilt(bench);
                UpdateBuildingPlayers(building);
            
                if (!_pluginConfig.BuiltNotification)
                {
                    return;
                }
            
                BasePlayer player = BasePlayer.FindByID(bench.OwnerID);
                if (!player)
                {
                    return;
                }

                if (!HasPermission(player, UsePermission))
                {
                    return;
                }
            
                if (_notifiedPlayer.Contains(player.userID))
                {
                    return;
                }
            
                _notifiedPlayer.Add(player.userID);
            
                if (GameTipAPI == null)
                {				
					if (!HasPermission(player, UsePermission))
					{
						return;
					}
					Chat(player, Lang(LangKeys.Notification, player));
                }
                else
                {
                    GameTipAPI.Call("ShowGameTip", player, Lang(LangKeys.Notification, player), 6f);
                }
            });
        }
