In expo-web-browser, currently openAuthSessionAsync in Android just opens openBrowserAsync under the hood in WebBrowserModule.kt. When using this package for authentication, there is no way to remove the minimize/picture-in-picture functionality that is build into CustomTabs. However, AuthTab provides a paired down version of CustomTabs that removes the minimize feature that is more streamlined for authentication. This seems like a better implementation for openAuthSessionAsync() method
