When I run the example from

https://github.com/jupyterlab/jupyter-renderers/blob/master/packages/geojson-extension/README.md

Instead of getting a rendered output, I get the following string:
<IPython.display.GeoJSON object>

This is with jupyterlab-geojson 3.3.1 and I'm also facing this issue on Google Colab

I've already tried restarting jupyter locally.
