Strange lights above Chicago area during storm that weren’t visible to the naked eye but showed up on camera.

Debated posting this, while flying out of Chicago on Friday evening 4.3.26, there was a storm incoming as we were going up in altitude. The storm looked really cool from a distance, so I wanted to film it for inspiration (I like to paint Bob Ross types scenes, side note I wish he painted more stormy settings. Angry clouds). I filmed a quick 10 second video to see if it would come out well (not really as you’ll see). But as I rewatched the video I noticed these flashing, maybe even moving lights way way above the storm line, flashing out of sequence with lightning flashes. I looked out the window again and could only see the storm, so I took my camera out and just pointed it at the storm and I could see the lights again. I took a few more videos, then asked the guy sitting next to me if he could see any flashing lights. I think he was a bit annoyed I interrupted his kindle time, he kind of rolled his eyes and said “yeah, there’s a storm out there”. I showed him the video, and he started geeking out, getting his own phone out to take a few vids too. Has anyone else ever seen this? These lights weren’t visible to a naked human eye but cameras were able to pick them up? PS - I’ll be pointing my camera out the window periodically to forever now when I’m flying haha.
