It should display if you enable "experimental plugins":

Thanks, that allowed me to install the plug-in, but I still don't see it from the plug-ins menu.
Do I have to have anything selected for it to show up? The instructions say 'Select the features that you want to use. The "Select Features by Polygon" tool works great if you only want to use a small part of a large network.' but when I select the OpenStreetMap layer (I want to select certain street segments and find the minimal path to walk all of them) all the select options are grayed out.

Ah, it may be beacuse there is an error initializing the module, I didn't see this until I restarted:
Couldn't load plugin 'chinesepostman' due to an error when calling its classFactory() method

Hi @michael-ts, how did you solve the gcd import error? I'm running into the same issue here (Ubuntu 22.10).
