Does MultiPolygon support Altitude?

I have a GeoJSON of type MultiPolygon that includes altitudes. When loading it with earth engine (ee.FeatureCollection), I receive an error, that the Geometry is invalid. The underlying code suggests that the MultiPolygon must only have arrays of 2 elements. This is an example MultiPolygon I am using:` [[[[0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0]]]] ` Does MultiPloygon only supports 2D coordinates?
