Roonserver doesn’t see dac but roon core does

Hi. I’m setting up a new mac mini as a roon core with a usb direct to my bifrost2. I noticed the roonserver download and thought it would be a better choice for my headless mac but using the app on my ipad i am not given the choice to enable devices and only have the mac’s speakers as a choice
When i install the full roon dmg i am able to enable the bifrost2 and the app sees it as well.
I will use roon vs roonserver for now and configure it to startup automatically, am really curious about how to get roonserver to see the dac though.
Thanks for any help.
