How to remove trader custom action

[dan3ko 0]

Hello. 

I have add an action to trader for run a custom mision and I want to remove it when used. The action added is this:

class Soborno
	{
    targetType = 2;
    target = "Exile_Trader_Office";

		class Actions
		{
			class Sobornar: ExileAbstractAction
			{
				title = "Sobornar al mafioso";
				condition = "true";
				action = "[] execVM 'addons\convoymision\sobornar_trader_fnc.sqf';";
			};
		};
	};

With this include in config.hpp in mission directory:

class CfgInteractionMenus
{
	#include "addons\convoymision\sobornar_Interaccion.hpp"
};

I have read in BI forums that with this code can remove it, but I don't know how to run, insert  the code: 

class CfgActions {
    class UseMagazine {
        show = 0;
    };
};

I try to run it with

[] execVM "filename.hpp";

but doesn't work. 

Can anyone help me?

Thanks.
