Loop Audio File

I have a little Membrane Pipeline with a video, and some audio tracks. I want to add some background music to it. A short track, that just loops over and over, until the video is done.
I've looked at doing something like:

          child(:mp3_source_bg, %Membrane.File.Source{
            location: state.background_audio.path,
            seekable?: true
          })

          child(:mp3_source_bg, %Membrane.File.Source{
            location: state.background_audio.path,
            seekable?: true
          })

and now I need to send a seek event to that child as far as I understand. However, I can't find any examples of that. How do I send this child an event?

    event = %Membrane.File.SeekSourceEvent{
      start: :bof,
      size_to_read: 100,
      last?: false
    }
    get_child(:mp3_source_bg) |> ????

    event = %Membrane.File.SeekSourceEvent{
      start: :bof,
      size_to_read: 100,
      last?: false
    }
    get_child(:mp3_source_bg) |> ????

Any tips?
