How do you programmatically create subtype group layers using the sdk api? LayerFactory class has methods to create feature layers, group layers, and layers. But no method to create Subtype Group Layers.
This API is now available in Pro 2.4 release:
ProSnippets MapAuthoring · Esri/arcgis-pro-sdk Wiki · GitHub
Unfortunately this isn't possible using the Pro SDK in 2.1 or 2.2. We will try to add it to a future release.
Thanks for looking into this and for your update.
