Help! Get Dictionary values using frida-il2cpp-bridge

[quagpz0]

I'm trying to get the values of this field using frida-il2cpp-bridge

// GameManager
// Token: 0x0400023C RID: 572
[Token(Token = "0x400023C")]
[FieldOffset(Offset = "0x98")]
private Dictionary<int, string> adjustConversationLevels;

It's System.Collections.Generic.Dictionary`2[System.Int32,System.String]

and this is my code

 let unityframework = Il2Cpp.domain.assembly("Assembly-CSharp");
  const GameManager = unityframework.image.class("GameManager");
  let adjustConversationLevels = GameManager.field("adjustConversationLevels");
  let OpenLevel = GameManager.method("OpenLevel");

  OpenLevel.implementation = function (this: any, level: any) {
    //trying to call adjustConversationLevels from here
    this.method(OpenLevel.name, 1).invoke(level);
  };

but there's no Il2Cpp.Dictionary so how to get those values?
