Mask in SVG

[Relison]

Is there a way to put a mask in SVG when viewing the camera?
I'm using zIndex, but even so it doesn't stay in front of the camera

It would be to put this mask in front of the camera.
Thanks!

You can use https://github.com/react-native-masked-view/masked-view to add a mask

Whenever I use any mask, it stays behind the camera, but the react-native-document-scanner plugin seems to open on top of the application.
