hook method from singleton class

[surbiks]

hi
i have singleton class in my app. i whant to hook some method but its not work.

class:

class GameScore : UnityEngine.MonoBehaviour
{
    System.String LNFBGMBOIDH; // 0x10
    static System.Object KKAFGOHJKCB; // 0x0
    static GameScore HMAGLKDOMNH; // 0x4
    static System.String DOIBHAOABFC; // 0x8
    System.Void FODFIBGMJKN(System.String MEBLAIILABK, System.Int64 ONAELMJBNFI, System.Net.HttpStatusCode HNIOMPMILFI);
    System.Void BHPIPOMLKDD(RestSharp.RestRequest CHAPFGLEGLK, System.String EHPFDFGKHNF, System.String MEBLAIILABK);
    System.Void PJHMGLEIKKD(RestSharp.RestRequest CHAPFGLEGLK, System.String EHPFDFGKHNF, System.String MEBLAIILABK);
    static GameScore BGCPLHLPPMM();
    System.Boolean IABIOLMMJBL();
    System.Void .ctor();
    Newtonsoft.Json.Linq.JObject POHMCOACLEG(System.Net.HttpStatusCode ALOGMCELJPO);
    System.Void IDBMFKCNPNN(Newtonsoft.Json.Linq.JObject NMGHPLHCLOG);
}

code:

import "frida-il2cpp-bridge";

Il2Cpp.perform(() => {

    const CSharp = Il2Cpp.Domain.assembly("Assembly-CSharp").image;
    const gameScore = CSharp.class("GameScore");

    gameScore.method("IDBMFKCNPNN").implementation = function(value: Il2Cpp.Object) {
        
        console.log("run from hook, add code")
        
        this.method("IDBMFKCNPNN").invoke(value)
    }
});

problem is when function IDBMFKCNPNN is invoked, in line this.method("IDBMFKCNPNN").invoke(value), this type is Newtonsoft.Json.Linq.JObject and show error JObject not have any IDBMFKCNPNN method.

See #237 (comment)

In short: IDBMFKCNPNN is a static method
