not working nor showing in the jupterlab 2

Hello,

Checklist prior to opening an issue

• I have followed fully the installation steps laid out in the documentation site.
• I have restarted jupyterlab.
• I have read the FAQ section in the documentation site.

Describe the bug So I installed the formatter, restarted jupyter lab, but I cannot see the format button in the taskbar, nor in the context menu after right-click. As if nothing was installed.

Hi @jajcayn, that’s a bit concerning, from the diagnostic commands output you posted, it should have worked… Is there anything weird in the terminal you launched jupyterlab? And also any weird in the console of your browser?

EDIT: Actually why is there a

Is the docs not clear? Please submit a PR if so 🙏 The need for changing the default formatter is documented here

And the keyboard shortcuts is because you didn’t change it to jupyterlab_code_formatter:autopep8

Please please please open a new issue next time, I don’t like commenting on closed issue especially when it’s not related to the original issue.
