How to implement login through VK in the web version and mobile application using the same AppID?

Question

Django

I am developing a mobile application for my small project, and it implies authentication through Facebook and VK. I use react-native (expo) for mobile applications, on the django backend, python-social-auth and django-rest-framework.
For Facebook, I use the following approach: I authorize natively through Expo Facebook , getting an access_token, send it to my endpoint on the backend, check if there is such a user, if not, I create it. The bottom line is that for Facebook one AppID can be used for all platforms, for VK you need to create separate applications in VK Dev . Accordingly, it will not work to check the access_token in my endpoint using the AppID for the web version.
How true is this approach in general and what are the alternatives and best practices?

Answer 1

I will answer my own question: I use WebView to get a token, but of course I refused to be "native".
