Outdated mqttListen.js Frida Gadget for Version 341.1+

[OpenSaned]

I'm trying to make a Python counterpart to this library, so I tried to run mqttListen.js on frida to introspect the MQTToT connections, the MESSAGE_ENCODER_SEND should be set to X.VGQ on version 341.1, but that particular function just never gets triggered. Other than Frida, externally analyzing the connections with something like Mitmproxy (Charles & Burp don't support MQTT) is the only solution I could think of. I'm not much of an expert on Frida or RE in Android, so...

If you've found a recent approach, or at least the right direction or resources, that would be very much appreciated.

Regards.
