Elementor category vs WordPress category

[bkantique]

Hi

Sorry for this stupid question but can you explain me the difference between the Elementor Category and the Wordpress category

I created custom post type with Pods and in the advanced options I can activate several Taxonomies:
Categories (Category)
Categories (Elementor_library_category)

I need category (for some filtering actions) so I am wondering which one I should use

Maybe these 2 categories don't have the same usage at all so my question

thanks
BR
