Can anyone show an actual example of a line using compress or decompress with Zlib\_jll?

Zlib isn’t a particularly easy library to use. Your best bet is to look at the source code of one of the Julia packages that depends on it, e.g. [CodecZlib](https://github.com/JuliaIO/CodecZlib.jl/tree/master/src).
