How to record an FX track - I cannot find the FX input in the Audio track

I am trying to record a DDL FX channel. One of the posts here said to add an audio track and select the FX track as an input. I see no such option to select the FX channel.
I am using no outboard gear, only a Presonus USB Audiobox for a mic and one MIDI input.
Please advise. Thanks in advance.

Option B:
You can also render the FX to a new track via the export option.
