Overbridge in Cubase when using different Interface

Has anyone managed to record multiple channels via Overbridge in Cubase, when using a different Audio Interface, i.e. not using the DT as the interface?

I tried to follow BoBeats older guide: https://www.youtube.com/watch?v=2UDUYdAwGRo

However the individual DT input tracks do now show up at all. So I can’t route them to the fake outputs… Any ideas, has anyone done this with the latest overbridge release?

This is on Cubase 10.5 pro, WIN

thanks
