Compatibility with Jupyterlab 5

Hi, Thanks for sharing the modifications for conda modules.

After installing this package I do get the modules tab but no module is displayed.

I run Jupyterlab 5 but I don't see any warning or error related to this plugin printed anywhere (I have set debug = True everywhere).

Here are the only modifications I did:

I don't really know how to debug this, do you have any idea ?
