    "rpcid": 1,
    "rpcstatus": 1,
    "rpchandle": 1, // optional field
    "protos": [
        {
            "method": 1,
            "request": "<b64 encoded string>", // <--- How do we obtain this?
            "response": "<b64 encoded string>" // <--- How do we obtain this?
        },
        {
            "method": 106,
            "request": "",
            "response": ""
        }
    ]
}

What are the functions that should be hooked with frida to obtain request and response?
