Is it possible to access the phone's camera through WebView?

Question

OpenCV

It is required to perform the following task, though I do not know if this is possible or not.

Through React Native WebView, you need to access the phone's camera to recognize objects
using the OpenCV library, on the server, using Python, a script is running that recognizes objects through the Web camera, I would like to make the recognition and selection of objects work through the phone's camera.

Whether it is possible to implement it somehow?

OpenCV has its own SDK for Android / IOS but I would like to use a server-side solution using Python and not write code in Java / Objective-C

I also managed to get access to the front camera, but this is not what is required for my task .
