startCamera seems to always pick the default camera for me, regardless of what I pass into it. I am calling it as follows; the same object being passed into `mediaDevices.getUserMedia` definitely changes.

```auto
        let videoConstraints = {
            deviceId: { exact: videoDevice.deviceId }
        };
        if (deepAR) {
            await deepAR.stopCamera();
            await deepAR.startCamera(true, {
                audio: { deviceId: { exact: audioDevice.deviceId } },
                video: videoConstraints
            });
        } else {
            const stream = await navigator.mediaDevices.getUserMedia({
                audio: { deviceId: { exact: audioDevice.deviceId } },
                video: videoConstraints
            });
            videoControl.srcObject = stream;
            videoControl.play();
        }

```

Any help is greatly appreciated!
