In our Android app, we're using a Chrome Custom tab to implement an OAuth-based login flow, as outlined in this video: https://www.youtube.com/watch?v=DdQTXrk6YTk
One issue I'm having is the Custom Tab menu: in the top-right section includes a way to "break out" of the Custom Tab and launch the login page in the "full" Chrome application:
Is there a way to disable this "Open in Chrome" menu item, or hide the entire menu? The only API I've found is to add menu items, not remove them: https://developer.android.com/reference/android/support/customtabs/CustomTabsIntent.Builder#addmenuitem
