You can get any and all of their old stuff on GitHub for free, however it might probably won’t work any longer. Facebook more than likely has been changed.
Most of the social media platforms make their money (lots of money) keeping folks on their platform by advertising and gathering and selling information on those people.
It’s not in their interests to allow you to use the content outside of the platform.
Have you tried the stack from GitHub?
If I remember correctly, it still works. I have used it some time ago, but I am not sure if I had mad changes to it.
(I deleted it already, otherwise I would be happy share it)
It’s there. Just download the whole package (aka “repo”) by clicking on the green button “code” and select “download zip”. Unpack it and then install the stack. It might work.
