Reference Layer Symbology and Field Names

[MatthewKohberger]

Hi, everyone.

I have built a Power BI application that utilizes ArcGIS maps on one of its pages.  The ArcGIS map displays a reference layer I created in ArcGIS Desktop and uploaded to ArcGIS Online.  The symbology and attribute information I defined in the data set's ArcGIS Online Hosted Feature Layer does not carry through to Power BI.  I have two questions:

1. How do I set up the symbology of the reference layers I add to ArcGIS maps in Power BI? 
2. How do I assign the field names that pop up when I select the features in the reference layers?

Thanks!

Matt
