So i had this same requirement 4 years ago. I wrote a small python script that used selenium to open chromium and cycle through tabs https://github.com/RemakingEden/ski-lodge-tv-slideshow/blob/master/skiLodge.py
Don't judge me on my 4 year old code, Im sure that it is awful but it did work then, perhaps you could try something similar?
No worries, i hope it works for you! Perhaps its a worth open source program if its not already created. An electron app that takes urls and a timeout value and then just cycles through.
