How to give a rust program access (permission) to my camera?

Question

I'm using uvc to try and get frames from my webcam. Everything is working up to the point where I try and open the webcam device.

Code:

use uvc::{Context, Frame};

fn main() {
    let ctx = Context::new().expect("Could not create context");
    let dev = ctx
        .find_device(None, None, None)
        .expect("Could not find device");

    let devh = dev.open().expect("Could not open device");
}

Error:

thread 'main' panicked at 'Could not open device: Access'

This is all just part of an example in the Uvc github, really I don't have any clues of what's going on. I'm using Ubuntu 22.10.

I've tried using sudo cargo run instead, but rust isn't installed for root user, so it didn't work. I'd also prefer to avoid sudo if possible.
