runpod.serverless has no attribute progress_update (runpod_python 1.7.12)

I've been given a task to look into an existing serverless handler written in python. I updated the dependencies, and now I'm getting

runpod.serverless

runpod.serverless

has no attribute "progress_update". I looked into it, and it seems that it's defined in

rp_progress

rp_progress

, which is not being exposed as a module? is this intentional? is there a different feature that exposes the same functionality that is undocumented, or am I doing something wrong? It's been the first time in forever that I did any python aside from really small scripts, so I might actually be missing something.
