Hello,

I tried to display my gmaps figure with jupyter notebook and got the following issue:

Failed to load model class 'FigureModel' from module 'jupyter-gmaps' Error: No version of module jupyter-gmaps is registered at f.loadClass (http://localhost:8888/lab/extensions/@jupyter-widgets/jupyterlab-manager/static/134.402424ef4079078b2e0e.js?v=402424ef4079078b2e0e:1:74855) at f.loadModelClass (http://localhost:8888/lab/extensions/@jupyter-widgets/jupyterlab-manager/static/150.1a6d6a3a0542a41bec5a.js?v=1a6d6a3a0542a41bec5a:1:10729) at f._make_model (http://localhost:8888/lab/extensions/@jupyter-widgets/jupyterlab-manager/static/150.1a6d6a3a0542a41bec5a.js?v=1a6d6a3a0542a41bec5a:1:7517) at f.new_model (http://localhost:8888/lab/extensions/@jupyter-widgets/jupyterlab-manager/static/150.1a6d6a3a0542a41bec5a.js?v=1a6d6a3a0542a41bec5a:1:5137) at f.handle_comm_open (http://localhost:8888/lab/extensions/@jupyter-widgets/jupyterlab-manager/static/150.1a6d6a3a0542a41bec5a.js?v=1a6d6a3a0542a41bec5a:1:3894) at _handleCommOpen (http://localhost:8888/lab/extensions/@jupyter-widgets/jupyterlab-manager/static/134.402424ef4079078b2e0e.js?v=402424ef4079078b2e0e:1:73392) at b._handleCommOpen (http://localhost:8888/static/lab/jlab_core.d60feca9d7f8b1cbab1d.js?v=d60feca9d7f8b1cbab1d:1:1231498) at async b._handleMessage (http://localhost:8888/static/lab/jlab_core.d60feca9d7f8b1cbab1d.js?v=d60feca9d7f8b1cbab1d:1:1233488)
