Read brotli stream in chunks

There is a way of putting as input the original data to a new brotli stream and read in chunks the compressed data

   using (var compStream = new BrotliStream(myfilestream, CompressionLevel.SmallestSize, true))
   {compStream.read(23939 byte)
   }

   using (var compStream = new BrotliStream(myfilestream, CompressionLevel.SmallestSize, true))
   {compStream.read(23939 byte)
   }
