Record only Live Link data in Take Recorder

I’m able to capture mocap data in take recorder by using actors, however I get no results when using Live Link only as a source. An empty track loads with initial blendshape values in sequencer when I open the LL only takes. Is there any way to only record the live link data? Take Recorder documentation is a bit ambiguous on this :“You can easily record animations from motion capture linked to characters in the level, as well as actual Live Link data for future playback.”

Any help is appreciated
