Hide or remove a GPFeatureRecordSetLayer layer using python

[TomerAdmon]

I'm building a geoprocessing tool with a "Feature Set" input (GPFeatureRecordSetLayer) that will be used during the tool's execution. The result of the execution is a new layer with color indications that should be presented on top of the "Feature Set" for the user.

Any idea how to remove/hide the initial  "Feature Set" layer from the Python side? or maybe update that input layer to be in the bottom of the map.

I've tried to use the "arcpy.Delete_management(desc.name)" that was able to delete the layer, but also caused ArcGIS Pro to throw endless errors.

Another question that might help is:
Where is that input layer stored? is it possible to access that using "arcpy.mapping.MapDocument" maybe...

If you're trying to remove the layer, you want to be using the removelayer method of the map class. 

aprx = arcpy.mp.ArcGISProject("CURRENT")
mp = aprx.activeMap

mp.removeLayer("Featureset1")

A layer is not actually your data; it is just a representation of it. arcpy.management.Delete() is killing whatever data that layer is referencing.

Thanks @AlfredBaldenweck !!
Would that work if the Python script is executed from a geoprocessing widget in webappbuilder? or should I look for an alternative?

Actually not sure at all about this one. I'd say give it a try and then if it doesn't work, try the webmap RemoveLayer() method. If it's in a webapp, I'm assuming you're using web maps, as well, so that might be the way to go anyway?
