I am developing an app that uses a TWA activity to show the login screen (and perform login using OAuth2).

Currently, the login is entirely handled inside our own server, so the TWA hides the navigation bar as expected.

But we are extending the login functionality to also support external authority providers (like Google, Microsoft, Github, etc...).

The issue is that we don't "own" those hosts, so we cannot update the .well-known/assetlinks.json file to include our own application. So the TWA activity, when clicking the external provider login link, displays the browser navigation bar.

Is there a way to prevent displaying the navigation bar when we don't have control to modify the external URL host?
