[nvim noob] no idea how to set it up

[okuma10]

I added it to Packer in my Packer init.lua. Created a pretty-fold-config where I pasted the settings into an init.lua. But I don't see any changes. Is this supposed to work with custom folds or it auto detects. Also how to toggle it? Apologies if maybe asking the obvious but I'm a noob at nvim(and lua)
