ee.Feature.getMapId
An imperative function that returns a map ID and optional token, suitable for generating a Map overlay.
Returns an object which may be passed to ee.data.getTileUrl or ui.Map.addLayer, including an additional 'image' field, containing a Collection.draw image wrapping a FeatureCollection containing this feature. Undefined if a callback was specified.
