Hi @kshVijay,

The implementation is changed for adding additional tab or panel in Any admin page from 4.20. For that you have to create new widget for this additional panel.

nopCommerce already defined AdminWidgetZones. You have to use them and create component in similar way that we do in public area component & yes, don't forget to enable that widget from Widget List.

if you don't know which widget zone is used in that admin page then you can find widget zone by opening same view in any editor or VS.
