Is there a list of Apple Ipad/pod models that work with Livelink?

I don’t want to buy a thousand-dollar iPhone or even a new Ipad/iPod. I just can’t afford that.
I’ve seen that some of the older models will work with Livelink and metahumans.
Is there a list of older apple iPad/pod models that can be used with LiveLinks facial mocap? I’d like to get even a refurbished iPad or something affordable to use as a facial mocap camera.
Do these need the LIDAR camera or just a certain chipset in them?
I’m still hoping for something for my Pixel 4XL as well as it seems to have depth capabilities as well.
