Does not work with jupyter-collaboration / RTC

[michaelchia]

Description

jupyterlab-unfold does not seem to support jupyter-collaboration as it is unable to handle the RTC custom drive path prefix (RTC:)

Reproduce

1. pip install jupyterlab-unfold jupyter-collaboration
2. Start jupyterlab
3. Click into any folder
4. Try to create a new file/folder
5. See error 'No such directory: RTC:'

Expected behavior

Able to create/move files/folders in directories using the UI.

Context

jupyterlab-unfold==0.3.3
jupyter-collaboration==3.1.0
jupyterlab==4.3.5
