It would be helpful to expose the "Manage Cache" functionality for a Scene Layer - 3D Object with the ArcGIS Python API so that updating the scene layer cache to reflect any changes made in the feature layer used to publish the scene layer can be done programmatically.
I have a workflow where many edits are made to attributes that control symbology on the feature layer used to publish the scene layer. The new symbology needs to be reflected in the web scene. It would be preferably to do this on some set interval, likely several times a day with a scheduled task or after some volume of edits via web hook rather than rely on a user to remember to do it manually.
