Theta Z1 ATEM mini streaming via HDMI

Hi I was trying to connect my theta Z1 to a ATEM Mini switcher to be hable to use it in a stream as one of the multiple cameras, the atem mini only supports HDMI inputs, so I connected the camera via an USB-C to HDMI cable, but the camera doesn’t show the option to enter the live mode, and the feed is black in the pc.

Is there any way to solve this? Is there any plugin? I tried to search but didn’t find one, and/or any information related to this topic

thanks for any help
