WSL: umake doesn't list pycharm

The umake docs (both online and on my ubuntu installation) say that umake ide has options including "pycharm,pycharm-educational,pycharm-professional". However when I try this on Ubuntu20 over WSL:

umake ide pycharm

I get -

... umake ide: error: argument framework: invalid choice: 'pycharm'(choose from 'arduino', 'atom', 'clion', 'dbeaver', 'datagrip','eclipse-cpp', 'eclipse-jee', 'eclipse-javascript', 'eclipse','eclipse-php', 'goland', 'idea', 'idea-ultimate', 'lighttable','netbeans', 'netbeans-html', 'netbeans-jee', 'phpstorm', 'processing','rider', 'rubymine', 'spring-tools-suite', 'sublime-text','visual-studio-code', 'webstorm')

As suggested by other answers here, I did

sudo add-apt-repository ppa:ubuntu-desktop/ubuntu-makesudo apt-get update

With no success. Is this a known WSL issue? Or am I missing something?
