Is possible to use a custom DEM data in the Elevation Profile Widget for AppBuilder?

[FeixRui]

Hi. Can I select a custom elevation data when using the Elevation Profile widget (using Webapp builder for ArcGIS)? The widget always uses the ESRI maps default (24m in Australia). I have a High resolution Elevation data (15cm) available and I would like to use it.  I tried to change the URL of the DEM I have but always showed as invalid. The figure below is showing the default URL of the widget.

Any help?

Thanks in advance
