What is the difference between enr.results and enr.res2d?

I found the following code while looking at GSEAPY's documentation.
# categorical scatterplot ax = barplot(enr.results, column="Adjusted P-value", group='Gene_set', # set group, so you could do a multi-sample/library comparsion size=10, top_term=5, figsize=(3,5), color=['darkred', 'darkblue'] # set colors for group )
and
ax = barplot(enr.res2d,title='KEGG_2021_Human', figsize=(4, 5), color='darkred')
I don't quite understand the difference between these two, especially why we need to use enr.results and enr.res2d. What is the difference between these two?

enr.res2d only stores the last gene_set while enr.results contains all gene_sets

.res2d is a common interface in all modules in gseapy
