  [[[102.0, 2.0], [103.0, 2.0], [103.0, 3.0], [102.0, 3.0], [102.0, 2.0]]],
  [[[100.0, 0.0], [101.0, 0.0], [101.0, 1.0], [100.0, 1.0], [100.0, 0.0]],
  [[100.2, 0.2], [100.8, 0.2], [100.8, 0.8], [100.2, 0.8], [100.2, 0.2]]]
]);

var flatten = turf.flatten(multiGeometry);

//addToMap
var addToMap = [flatten]

Returns FeatureCollection<any> all Multi-Geometries are flattened into single Features
