Greetings!
Is it possible to add WAB custom themes in ArcGIS Enterprise the same way you add custom widgets?
If not, is there any other way to do it?
I have created a custom theme in WAB Developer Edition 2.23 and follow this guide
https://enterprise.arcgis.com/en/web-appbuilder/latest/create-apps/add-custom-widgets.htm
I pointed to the theme manifest.json file, but it only add it as a widget instead of a theme that can be used within the organisation.
