Need Help: How to add the metadata to PNG

[barepixels]

I am stumbling my way through here haha. Jumping into the water and see if I could learn GitHub and Python.
Love Fooocus but unlike any other Stable Diffusion UI it doesn't save the metadata to the PNG nor has the ability to load settings from the embedded PNG files back into Fooocus. If you know how, please show me. Once I learn how to I plan to synch with lllyasviel's Fooocus weekly.
