Detect if coordinates are in camera's field of view

Hi, I’m currently playing with some of the Expo API features, such as Gyroscope and DeviceMotion. Let’s say I put a pin on a map. I want my app to be able to show something on augmented reality at the pin’s exact location, when the camera of my phone is pointing at it.

Any idea how I could achieve that?

I’m of course not looking for an exact solution, but just some tips or advices which could help me.

Thanks!

Did anyone ever find a way to make this happen? I’m apart of a group that’s working to make this a functional part of our project.
