Question HDMI to USB-C converter

[vkjanzen]

My first post - so excuse me if this is incorrect place. I volunteer @ church on tech team due to "some knowledge". We stream to Facebook using a PTZ-Optics camera into OBS software to facebook live. Currently camera is connected via network IP - but it and audio from a Yamaha soundboard are out of sync. We need a way to connect the HDMI from the camera into the Windows 11 computer preferable to a USB-C port. Computer has no HDMI in port. Any suggestions for an HDMI to USB-C converter - or any experience doing this?

Thanks in advance - appreciate any advice.
