Integrate react-native (web) into Django. How to add a prefix to all urls?

Question

I'm using react-navigation and trying to figure out how to add a prefix to all endpoints. Follows my LinkingConfiguration which doesn't do what I want:

// const prefixes = [Linking.makeUrl('/app')];
const prefixes = ['example://app/', 'https://example.com/app/'];

const RootLinkingConfiguration = {
  prefixes,
  config: {
    screens: {
      Root: {
        screens: {
          Activity: {
            screens: {
              TabOneScreen: 'activityone',
            },
          },
          NewNfe: {
            screens: {
              Camera: 'camera',
              PostURL: 'posturl',
            },
          },
          Report: {
            screens: {
              ReportScreen: 'report',
            },
          },
        },
      },
      NotFound: '*',
    },
  },
};

I would like all endpoints to be prefixed by app, i.e:

app/activityone
app/camera
app/posturl
app/report

But I wouldn't like having to change them individually. How can I do this?

On the backend side I am pointing all urls starting with app/... to my react app. But I can't navigate properly with deep-links because my react-navigation linking configuration does not contemplate the app prefix.
