Here's an example how you can join a twitch stream with its chat in a single video.

First download the video in the desired quality:

twitch-dl download -q 1080p 2237172069 -o video.mp4

Render the chat with the same height as the downloaded video:

twitch-dl chat --dark --width 500 --height 1080 2237172069 -o chat.mp4

Stitch them togheter using ffmpeg:

ffmpeg -i video.mp4 -i chat.mp4 -filter_complex hstack=inputs=2 chat_with_video.mp4
