I am working with ArcGIS Experience Builder Developer Edition to build an application. How I understand the docs and how it is described here, the basemap gallery shown in the application should be the one from the organisation (ArcGIS Enterprise).
However, this does not seem to work for me. Even though I have a basemap gallery defined in my Portal for ArcGIS (which works in the Portal), my application shows a different list (ESRI basemaps). This is the list I get:
Any idea what I am doing wrong? Do I lack some configuration somewhere? The connection between the application and my Portal seems to be fine, as I draw all my data and a Geocoding service from it successfully.
