How to know if user clicks on "Open in X browser"?

[ahmadwrites]

When using the openAuth method, and if the user has other browsers downloaded, they have an option to "Open in Chrome" for instance. For android, it seems like the task is continued and they are able to process the callback even if they move to another browser for the authentication. For IOS however, the process is detached so even if the deeplink goes back to the app, the flow that initiated the openAuth won't know that it has come back. Is there a way to detect this? Ideally this can be fixed by either allowing it to get back the deeplink params back into the app from the external browser or by blocking the authentication if they open up the browser instead of using our in app browser itself.
