, which has a function called Private.ansiSpan
but it's not exported...OutputArea

I have a question about theme: After I installed a theme extension, the newly installed theme won't appear in the Settings -> JupyterLab Theme submenu. How can I fix this?
Well it turned out to be a problem described in this issue jupyterlab/jupyterlab#8122 . I deleted build_config.json
and everything works fine!
