Running a DAW + OBS: multiclient ASIO?

I have a UR816C and I’m trying to run Reaper and also OBS. I’m only playing tracks in Reaper, not recording. (but it would be nice to record as an option). But I need the audio routed to OBS to broadcast. It doesn’t seem like the Yamaha ASIO driver is multiclient, is it?

I can get the audio into Reaper, but when I open OBS, I’m not sure what audio source will work.?
