Does anyone know how to consume REST services within Web app builder, that are not added into the initially created web map. I want to be able to work with (consume) services without linking the service into the web map.
If I want to add a REST URL into my map, without adding the REST service into a Web Map (1st); can I use the FeaturelayerServiceBrowser class to accomplish this? https://developers.arcgis.com/web-appbuilder/api-reference/featurelayerservicebrowser.htm
How can I add data layers to the Web APP without first adding the layer into a web map? Can I directly pull JSON (GeoJSON?) data into the web map like this:

https://community.esri.com/thread/17970
All I can find is the link below that says this type of work flow is not supported.
