It’s all iMac is it compatible also with IPad Air?

I am having a really hard time finding any way to use a webcam on my iPad Air. 5gen. I have a webcam (BEJOY) supposedly plug and play. Definitely not. I have a usb hub with c interface. Have tried apps. I have even tried to write my own code for it. I tend to overthink things. Any ideas??? I will mention you in my webcast or not if you like.
