PSA Controller Car - Addon set up / OTP Config

However, I still get prompted for the SMS which never arrives, however the web UI does eventually update to show:

Now, fair warning, I am a complete beginner at HA, Python, etc. and (probably incorrectly I’m realising now) thought that once I got HA up and running, installing the PSA Car Controller add-on would be like installing an application on my laptop or app on my phone ie. enter the MyPeugeot login credentials and it would work.

Following the info here: GitHub - Flodu31/HomeAssistant-PeugeotIntegration: Integration between Peugeot API and Home Assistant
I’ve updated the sensor & configuration script, changing the “IPofTheSoftware” to that of my HA, and the “YourVIN” to the VIN of my car throughout the code, but I still don’t seem to be getting anywhere.

Any help anyone can offer would be greatly appreciated.
