FX30 live stream to Resolve Studio 19.01 via USB C?

Am able to live stream FX30 to LU-Lite, Zoom, FaceTime, et al., yet Resolve Studio 19.01 allows USB C connected FX30 to be selected as Video Source in preferences, yet the box for Video Monitoring immediately below is greyed out and does not allow one to select FX30 that Resolve did allow me to select as source. Given that I am able to run FX30 video and audio to every other likely suspect program, and also monitor it when FX30 is connected via USB C to latest Sonoma running maxed out M1Max, is there an explanation for why BMD apparently has disallowed one to capture and monitor a USB C connected FX30 in Resolve Studio? Far more tedious to connect FX30 via a BMD box (i.e., by running signal out via FX30's HDMI). Ideas, workarounds or explanation, anyone? Thanks.
