AudioQuest Dragonfly Red Squeezebox Touch set up

I’m New to Roon, I have Squeezebox Touch with EDO and Dragonfly Red usb DAC added via 2.0 USB hub. After reboots several times I have got MQA via tidal to play. My question is when viewing the signal path the Dragonfly is not seen the Touch is last in the chain should it be there? The Dragonfly lights up amber for 88khz, pink 96khz etc. Cheers

I would imagine because the Touch does not report an external dac is present it was after all an unofficial mod to get usb out.
