How to copy layer from one APRX map to another?

Question

Trying to get a graphics layer that was created from JSON (using the whole webmap to JSON workflow) from one map in APRX to another map using arcpy. I've tried this: myLayer = map1.listLayers("myLayer")[0] map2.addLayer(myLayer)‍‍‍ map2.listLayers()‍‍‍‍ The layer now shows up in the layer list. But I can't see it in the map. So I tried this: layerDef = json.loads(Web_Map_as_JSON)['operationalLayers'][<index of layer>] map2.addLayer(map1.listLayer("myLayer")[0] map2.listLayers("myLayer")[0].updateLayerFromJSON(layerDef) ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Everything runs without errors. I just don't get the added layer to display. Any suggestions?

Last ditch effort to find someone who knows... These are steps I have taken to get me to where I am. * Export JSON from web map * Use Python to turn web map into APRX using a layout with 2 map frames.* The MainMapFrame gets all the layers from JSON.including graphics created in web map. * The other map frame gets layers as declared in layout template. * Now, I'd like to copy one of the graphics layers from MainMapFrame to the other mapframe. * So that I can print it all to PDF. Nothing has worked so far. I even tried this: myLayer = map1.listLayers('myLayer')[0] myLayer.saveACopy(r"...\myLayer.lyrx") map2.addLayer(arcpy.mp.LayerFile(r"...\mylayer.lyrx"))‍‍‍ Both map frames have same spatial reference and share other common service layers that display without any issues. Must be something about graphics.

Wanted to add a little more context in the hopes of garnering some feedback. Using ConvertWebMapToArcGISProject to create a map. Now as part of the JSON, I'm ending up with a graphics layer. It looks something like this: { "mapOptions": { ... }, ... }, "operationalLayers": [ { "id": "defaultBasemap", ... }, { "id": "", .... }, { "id": "", "opacity": 1, "minScale": 0, "maxScale": 0, "featureCollection": { "layers": [ { "layerDefinition": { "name": "pointLayer", "geometryType": "esriGeometryPoint" }, "featureSet": { "geometryType": "esriGeometryPoint", "features": [ { "geometry": { "x": someX, "y": someY, "spatialReference": { "wkid": 102100 } }, ... } ] } } ] } } ] }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ I can remove from map by doing mymap.removeLayer(mymap.listLayers("pointLayer")[0] But I can't add this "pointLayer" to another map (see my first post). Is there any way to grab a portion of the JSON above... json.loads(Web_Map_as_JSON)['operationalLayers'][2] to define a layer and add it to another map? Such as ... json.loads(Web_Map_as_JSON)['operationalLayers'][2]["featureCollection"]["layers"][0] # doesnt seem to work ... or get some viable layer definition that can be fed into ... arcpy.JSONToFeatures_conversion() ... and then add those to the other map?
