If you want to remove layers you will need to remove them from the WebMap which the app is based on.

Is this still true?  I'd like to show just a couple of the webmap layers in my webmap app.

If you want to remove a layer from the WAB map in JS code then you would use.

this.map.removeLayer(this.map.getLayer("incidentLayer"));‍
