I bought two in the end, first one was the cable that was on Simonthewizard's website here: https://amzn.eu/d/00mA4CGK
and then I ended up buying this one from ebay: https://ebay.io/m/RnMHdO
which was a bit pricey. The amazon cable shows up as working fine in device manager as a USB serial. The ebay one shows up as Silicon Labs CP210x USB to UART Bridge and again working fine under device manager.
Tried multiple combinations with RJ12 plugs to get them working but no luck so far.
