Add New tab to Faceted Search Widget

[Feddy]

Hi Team , 

Please refer below image of OOB "Faceted Search" widget.

I would like to add new tab ( I observed that these auto populated based on AI Search Application) and on click of that tab I would like to call "search Page"(custom) widget. 

There is restriction to create new navigation tab's under AI search Application but I inserted using background script.  
I would like to know How can I add the new tab with in the "Faceted Search" widget and display search result (by calling custom widget). I am able to call the widget using widget id but not sure how to link it to a tab.

Any help on this would be much appreciated.

Thanks

These tabs are *only* based on the search sources. If you would like a new tab, you will need to add a new search source with the information you would like in the results for that tab.
