ATEM Mini Pro ISO - Record to SSD and Webcam for Riverside

Ok... I normally don't post on forums but I need the groups help here... and if this isn't possible I just need to know so I quit wasting my time.

I have an ATEM Mini Pro ISO... I want to record multi-cam to SSD AND have my Mac register the ATEM as a WebCam so I can send the feed through Riverside.FM for LIVE recording.

I know I can get the ATEM Extreme with two USB-C ports and this will solve the issue... however, this is the more expensive option.

Am I missing something here. Is there anyway to still record multicam using the HDMI out... or running a USB-C splitter so I can then you the dedicated USB-C to run to my Mac for Riverside.fm? Any help is appreciated, as I'm going crazy over here.

Any luck getting the ATEM Mini Pro ISO to record to SSD as well as Webcam? I need to do it as well.
