Help! My jupyter notebook doesn't display output of LeafMap library


I am trying to plot LeafMap using Jupyter notebook. I have imported leafmap.kepler and trying to plot a basic map (sharing the codes below), however I am unable to see the output in Jupyter notebook cell.

I have run the same code in my other laptop and its running well. Kindly help.

import leafmap.kepler as leafmap
m = leafmap.Map(center=[40, -100], zoom=2, height=600, widescreen=False)

I also tried running geopandas and display the map, its not working too.
