FaceNormalsHelper for BufferGeometry

I cannot use FaceNormalsHelper for BufferGeometry.

reason behind that line no 85 in FaceNormalsHelper.js

is there any other option for bufferGeometry.

BufferGeometry has no concept of face normals. You can only visualize vertex normals.

Hence, it latest releases FaceNormalsHelper is not available anymore.
