title: get storageKey from a sceneId
body: <p>I am trying to use the 3d.io API on a Node.js server to export a scene as a blender model. I have the sceneId for the scene, however the export API seems to only want a storageKey and I'm not sure how to get one from a sceneId. I have found issues that resolve this for the in-browser case, but not the server-side case.</p>
