Tuya Door Contact Sensor still unsupported

[winged pelican]

I have a few contact sensors from Tuya and found they are listed in Integrations as "Unsupported", however the Temperature ones work fine. I've tried to follow this thread on github editing the core .py files for /Tuya/ sensor.py and binary_sensor.py :
https://github.com/home-assistant/core/issues/108301

However, the device is still saying unsupported (contact sensor) . The github issue was closed however the issue still remains. Anyone followed this and made it work? Am I missing something? Many thanks,

I've downloaded the json diagnostics and it appears the category is listed as "tdq". Does that mean this bug/issue on github mentioning "mcs" is the wrong section and I should be using "tdq" in the py files?
