ArcGIS Online Public Data

Essentials 4.2.2 HTML5 2.3.3

We have published some data to be publicly available ArcGIS Online.  When I go to Add a Map Service in Essentials and click on the ArcGIS Online connection, nothing happens.  I can't get anything to show up for this connection.  When I cick the rest endpoint, I just get a bit of text back.

What am I missing?
