joydan2002/facebook-tools ? reverse-engineered prompt

Build me a simple Facebook tools app that bundles a few useful automation features into one place.

I want it to let me log in with Facebook cookies, then do things like send automatic Messenger chats, post an image to Facebook, unfriend people based on interaction, dump Facebook IDs, generate a token, change post privacy, and download Facebook videos. Keep it straightforward and easy to run, with a basic menu so I can pick what I want to do.

If some Facebook details or current methods have changed, look up the latest docs or common approach online and make it work as best you can. Make the interface clear, handle errors nicely, and keep the code organized so each tool is separate but part of the same project.
