Projecting webcam livefeed on to a specific geometry (From Insta360 to OBS to Splitcam to Unity)

Hi,

I’m trying to project a live feed from insta360, using it as a webcam.
I have the webcam texture, as you can see in the screenshot. But I now want to project this onto the shape you see in the game (a half-dome basically) . How should I go about doing this?

Regards,
M
