Create Application Item has no Experience builder widget

[VickyWang_COM]

Hope someone point me to the righ direction. 

I have follow this post to  add the Experience Builder custom widget to ArcGIS Online. my understanding is that after 11.x the ArcGIS online or Enteprise can host the custom widget. 

however, when I use the ArcGIS online to add Application item -> there is no Experience Builder Widget as option to select !!

I am login as Administrator. not sure what else that I can check ... 
left photo the application item option from ArcGIS Online. the photo on the right-habd side is the arcgis post that I try to follow.

Hi @VickyWang_COM ,

Custom widgets are supported in ArcGIS Enterprise, but not in ArcGIS Online. So there is no Experience Builder Widget in the application type
