gstreamer hlssink is not creating a m3u file or multiple ts files - instead one gigaintic ts file

when running gstreamer with udp receiver pipeline the hls sink creates one gigantic file instead of creating multiple files

I want to stream the audio test source over the network, then at the receiving end save multiple files with playlist file using hlssink
