[Python] GStreamer pipeline using WebRTC

I'm now working on a project where I need to stream video in real time and save photos every a couple of minutes so I've started learning about GStreamer. I currently have a working pipeline using udpsink but I'm struggling a lot with WebRTC (I'm now trying to migrate to a web base application). I understand how WebRTC works but whenever I try to build something I failed misserably. I've found this repo: https://github.com/imdark/gstreamer-webrtc-demo/tree/master

I have problems making it work but I found it easier to ask for a specific code that I suppose works that building my own from 0. I can't find any tutorials and readme files aren't helping much. I'm building my project with python so I tried to use that part of the repo but I always encounter problems. I've used Docker before but not with anything showing on screen. When I make docker compose with the gst (that calls executable in C not Python but to try) doesnt show anything on screen. Then if I start simple server on signalling folder it loads correctly but when I launch the clients I always get errors like this one:

./session-client.py
Our uid is 'ws-test-client-a7e4e8'
Traceback (most recent call last):

So basically I would need a brief tutorial on make this works, if this repo really works. Or another tutorial using Python for gstreamer and webrtc. Thanks in advance and have you all a great day
