I wonder if it is possible to create a simple map in Experience Builder, which would just show polygons, without the underlying base map, boundaries/borders of underlying base map? When you import an existing map created in My Content, it comes surrounded by a standard box/border etc, I'm trying to get a visual akin to simple choropleth map created in MS Powerbi, with the polygons not created using the ArcGIS mapping tool in Powerbi. Also would it be able to custom format the pop-up boxes on the map in Experience Builder?
