API add_geojson_layer() does not project correctly

Description

I am testing loading a shapefile converted to geojson via geopandas into jupyterGIS. From the API the shapefile is incorrectly projected, however when I load it from the graphical interface the projection is correct. I have an example notebook here:
https://github.com/johnjarmitage/CSS-jupytergis/blob/main/notebooks/france-sediments.ipynb

Here is an image of the correctly loaded shape file (blue) and API loaded shape file (black).

It looks like the API is not picking up the correct coordinates, perhaps they are the original Lambert 93 coordinates of the dataframe and not the reprojected coordinates? But I don't see how this could happen.
